existing modern devices and the legacy wrappers to work in this
environment. This in general greatly simplifies writing a modern
device. [Aaron Giles]
General notes:
* some more cleanup probably needs to happen behind this change,
but I needed to get it in before the next device modernization
or import from MESS :)
* new template function device_creator which automatically defines
the static function that creates the device; use this instead of
creating a static_alloc_device_config function
* added device_stop() method which is called at around the time
the previous device_t's destructor was called; if you auto_free
anything, do it here because the machine is gone when the
destructor is called
* changed the static_set_* calls to pass a device_t & instead of
a device_config *
* for many devices, the static config structure member names over-
lapped the device's names for devcb_* functions; in these cases
the members in the interface were renamed to have a _cb suffix
* changed the driver_enumerator to only cache 100 machine_configs
because caching them all took a ton of memory; fortunately this
implementation detail is completely hidden behind the
driver_enumerator interface
* got rid of the macros for creating derived classes; doing it
manually is now clean enough that it isn't worth hiding the
details in a macro

More deprecat.h cleanup in the core, notably changing the apis for
poly_alloc. I also made cpu_get_index_slow fatalerror on failure
since no one is checking the return value.
deprecat.h -= 14, Machine -= ~55

Subject: [patch] Add machine to some emu/machine init methods
Hi mamedev,
This patch widens some machine init interfaces to pass the machine
parameter, allowing more Machine global references to be eliminated.
Eventually most of these need to be converted to devices, but this
change reduces the deprecation surface in the meantime. I also
attached the script I used to do the initial changes to the drivers,
which handled about 90% of the cases without further editing.
