This was a piece of emergent behaviour in the original implementation of
software media loading. It was preserved in the last big refactor of
ROM loading, but it can be removed now to simplify the code.

* util/chd.cpp: Allow caller to provide a helper for finding parent CHDs
and expose (recursive) missing parent status.
* emu/romload.cpp: Search parent systems/devices/software for parent
CHDs on encountering a delta CHD.
* emu/romload.cpp: Report error on delta CHDs when parent can't be
found.
* emu/romload.cpp: Check parents for matching CHDs with different names
for devices as well as systems and software.

osd: Supply OSD object to modules on initialisation. Encapsulated some
event handling in the OSD objects rather than leaving it in free
functions. Put various stuff in namespaces.
osd/modules/input: Enabled dinput, xinput and winhybrid modules for
Windows SDL builds, and enabled background input for dinput and xinput
(and by extension winhybrid) modules. Also fixed some COM and X11
resource leaks.
osd/modules/input/input_sdl.cpp: Flipped SDL mouse button order to match
Windows, and exposed vertical and horizontal scroll as Z and rZ axes.
Moved SDL UI event handling out of input devices into OSD object.
osd/modules/input_rawinput.cpp: Changed lightgun Z axis token so it's
correctly identified as a relative axis (it maps to the scroll wheel
equivalent).
osd: Added an option to choose the network provider module. Mostly
useful if you build with both TUN/TAP and pcap support included, or if
you want to disable emulated networking completely.
emu/input.cpp: Use a better strategy for assembling input code names
that uses fewer temporary strings and doesn't require use of the
non-Unicode-aware space trimming function (fixes MT08552).
osd/modules/input_dinput.cpp: Improved polling logic.
osd: Made various parts of the input code less dependent on concrete emu
objects, and reduced inappropriately passing around the machine object.
Made input modules less dependent on OSD implementation. Encapsulated
some stuff and got rid of some vestigial newui and SDL1 support code.
Cleaned up some interfaces. Moved OSD options classes to their own
files.
Prepare to remove main.h from emu.h - it's mostly used to get the
application name, which the vast majority of emulated devices don't need
to do.

Also made error messages for missing CHDs and missing files for software
parts using the image file loader show search paths, and changed the
(poorly named) bitbanger device to use the image file loader rather than
the ROM loader for software items.

Added more modern generic I/O interfaces with implementation backed by stdio, osd_file and core_file, replacing io_generic. Also replaced core_file's build-in zlib compression with a filter.
unzip.cpp, un7z.cpp: Added option to supply abstract I/O interface rather than filename.
Converted osd_file, core_file, archive_file, chd_file and device_image_interface to use std::error_condition rather than their own error enums.
Allow mounting TI-99 RPK from inside archives.

* Show list name in software selection menu (machines have multiple
lists).
* Actually report software list parsing errors during validation.
* Check that software list name attribute matches filename.
* Limit software list names to 24 characters - they're getting too long,
and they need to be practical in command lines.
* c128.cpp: Fix dangling reference to renamed software list.
-emu/ioport.cpp: Slightly better test for deselected slot cards.

- Remove corestr.h from emu.h; update a few source files to not use it at all
- Change strtrimspace, strtrimrightspace and core_filename_extract_* to be pure functions taking a std::string_view by value and returning the same type
- Change strmakeupper and strmakelower to be pure functions taking a std::string_view and constructing a std::string
- Remove the string-modifying version of zippath_parent
- Change tag-based lookup functions in device_t to take std::string_view instead of const std::string & or const char *
- Remove the subdevice tag cache from device_t (since device finders are now recommended) and replace it with a map covering directly owned subdevices only
- Move the working directory setup method out of device_image_interface (only the UI seems to actually use the full version of this)
- Change output_manager to use std::string_view for output name arguments
- Change core_options to accept std::string_view for most name and value arguments (return values are still C strings for now)
- Change miscellaneous other functions to accept std::string_view arguments
- Remove a few string accessor macros from romload.h
- Remove many unnecessary c_str() calls from logging/error messages

The things that were previously called device iterators are not
iterators in the C++ sense of the word. This is confusing for
newcomers. These have been renamed to be device enumerators.
Several Lua methods and properties that previously returned tables now
return lightweight wrappers for the underlying objects. This means
creating them is a lot faster, but you can't modify them, and the
performance characteristics of different operations varies.
The render manager's target list uses 1-based indexing to be more like
idiomatic Lua.
It's now possible to create a device enumerator on any device, and then
get subdevices (or sibling devices) using a relative tag.
Much more render/layout functionality has been exposed to Lua. Layout
scripts now have access to the layout file and can directly set the
state of an item with no bindings, or register callbacks to obtain
state. Some things that were previously methods are now read-only
properties.
Layout files are no longer required to supply a "name". This was
problematic because the same layout file could be loaded for multiple
instances of the same device, and each instance of the layout file
should use the correct inputs (and in the future outputs) for the device
instance it's associated with.
This should also fix video output with MSVC builds by avoiding delegates
that return things that don't fit in a register.

API impact:
- install_ram/rom/writeonly now requires a non-null pointer. If you want
automatically managed ram, add it to a memory map, not in machine_start
- install_*_bank now requires a memory_bank *, not a string
- one can create memory banks outside of memory maps with memory_bank_creator
- one can create memory shares outside of memory maps with memory_share_creator
Memory maps impact:
- ram ranges with overlapping addresses are not shared anymore. Use .share()
- ram ranges touching each other are not merged anymore. Stay in your range
Extra note:
- there is no need to create a bank just to dynamically map some memory/rom.
Just use install_rom/ram/writeonly

This should address at least some of the remaining issues from MT07410
and GitHub #7314. If this causes issues like MT07756 to reappear, it
will need to be fixed/reverted before release.

romload.cpp: reduce copy-pasta (nw)
(nw) I fixed the errors found by adding validation to software list data areas.
Most of them seem to be simple copy-paste errors hidden by the fact that the
default device_image_interface loader ignores the data area size (as opposed to
the "ROM" loader). There was one C64 cartridge with a missing zero on the data
area size that was pretty clearly wrong.

* More flexible constructors for path_iterator and emu_file
* More straightforward system/device ROM loading and software loading when using ROM loader
* Proper parent walk when searching for identical CHDs with different names from software list
* Fixed hangs if software item parents form a loop
* Fixed layouts being loaded from bogus empty paths
Note that there are changes in behaviour:
* For software list ROMs/disks, MAME will now search the software path before searching the machine path
* The search path for the owner of the software list device is used, which may not be the driver itself
* MAME will no longer load loose CHDs from the media path - it's just too unwieldy with the number of supported systems
* MAME will no longer search archives above the top level of the media path

* Add doxygen comments for bit manipulation functions
* Add an overload of BIT that works like the AArch64 UBFX instruction
* Kill off some of the silly concatenating overloads for emu_file::open
* Make searchpath acually useful for devices
This is a checkpoint - I'm planning to improve ROM loading behaviour at
least a little.

* Changed emu_fatalerror to use util::string_format semantics
* Fixed some incorrectly marked up stuff in build scripts
* Make internal layout compression type a scoped enum (only zlib is supported still, but at least the values aren't magic numbers now)
* Fixed memory leaks in Xbox USB
* There can only be one "perfect quantum" device - enforce that only the root machine can set it, as allowing subdevices to will cause weird issues with slot cards overiding it
* Allow multiple devices to set maximum quantum and use the most restrictive one (it's maximum quantum, it would be minimum interleave)
* Got rid of device_slot_card_interface as it wasn't providing value
* Added a helper template to reduce certain kinds of boilerplate in slots/buses
* Cleaned up some particularly bad slot code (plenty more of that to do), and made some slots more idiomatic

(nw) This has been a long time coming but it's here at last. It should
be easier now that logerror, popmessage and osd_printf_* behave like
string_format and stream_format. Remember the differences from printf:
* Any object with a stream out operator works with %s
* %d, %i, %o, %x, %X, etc. work out the size by magic
* No sign extending promotion to int for short/char
* No widening/narrowing conversions for characters/strings
* Same rules on all platforms, insulated from C runtime library
* No format warnings from compiler
* Assert in debug builds if number of arguments doesn't match format
(nw) Also removed a pile of redundant c_str and string_format, and some
workarounds for not being able to portably format 64-bit integers or
long long.

This effectively reverts b380514764cf857469bae61c11143a19f79a74c5 and
c24473ddff715ecec2e258a6eb38960cf8c8e98e, restoring the state at
598cd5227223c3b04ca31f0dbc1981256d9ea3ff.
Before pushing, please check that what you're about to push is sane.
Check your local commit log and ensure there isn't anything out-of-place
before pushing to mainline. When things like this happen, it wastes
everyone's time. I really don't need this in a week when real work™ is
busting my balls and I'm behind where I want to be with preparing for
MAME release.

Together, these changes enable softlist CD-ROM media changes for InterPro, and presumably other nscsi_cd systems. Haven't looked into how other CD-ROM devices work, but the romload fix should apply equally to them too.
* nscsi_cd: detect and respond to media changes
* romload: fix disk entry processing

Conflicts:
src/frontend/mame/mame.cpp
Sorry, but this change was half-baked. It breaks a lot of existing
functionality and clearly hasn't been tested in more than a tiny subset
of use cases. Please play this work back onto your own branch, and test
it before submitting another PR.

This is an overhaul to how MAME handles options to provide a better foundation for what MAME is already doing in practice. Previously, core_options was designed to provide an input/output facility for reading options from the command line and INI files. However, the current needs (image/slot/get_default_card_software calculus and MewUI) go way beyond that.
Broadly, this PR makes the following changes:
* core_options now has an extensibility mechanism, so one can register options that behave dramatically differently
* With that foundation, emu_options now encapsulates all of the funky image/slot/get_default_card_software calculus that were previously handled by static methods in mameopts.cpp. Changes to emu_options should not automatically cascade in such a way so that it stays in a consistent state
* emu_options no longer provides direct access to the slot_options/image_options maps; there are simpler API functions that control these capabilities
* Many core_options functions that expose internal data structures (e.g. - priority) that were only really needed because of previous (now obsolete) techniques have been removed.
* core_options is now exception based (rather than dumping text to an std::string). The burden is on the caller to catch these, and discern between warnings and errors as needed.
Obviously this is a risky change; that's why this is being submitted at the start of the dev cycle.
