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

Remove redundant machine items from address_space and device_t.
Neither machine nor m_machine are directly accessible anymore.
Instead a new getter machine() is available which returns a
machine reference. So:
space->machine->xxx ==> space->machine().xxx
device->machine->yyy ==> device->machine().yyy
Globally changed all running_machine pointers to running_machine
references. Any function/method that takes a running_machine takes
it as a required parameter (1 or 2 exceptions). Being consistent
here gets rid of a lot of odd &machine or *machine, but it does
mean a very large bulk change across the project.
Structs which have a running_machine * now have that variable
renamed to m_machine, and now have a shiny new machine() method
that works like the space and device methods above. Since most of
these are things that should eventually be devices anyway, consider
this a step in that direction.
98% of the update was done with regex searches. The changes are
architected such that the compiler will catch the remaining
errors:
// find things that use an embedded machine directly and replace
// with a machine() getter call
S: ->machine->
R: ->machine\(\)\.
// do the same if via a reference
S: \.machine->
R: \.machine\(\)\.
// convert function parameters to running_machine &
S: running_machine \*machine([^;])
R: running_machine \&machine\1
// replace machine-> with machine.
S: machine->
R: machine\.
// replace &machine() with machine()
S: \&([()->a-z0-9_]+machine\(\))
R: \1
// sanity check: look for this used as a cast
(running_machine &)
// and change to this:
*(running_machine *)

Also replace timer_get_time() with machine->time()
1. Main conversion
timer_get_time( *)\( *([^)]+) *\)
\2->time\1()
2. Cleanup #1
&machine->time
machine.time
3. Cleanup #2
&m_machine->time
m_machine.time

timers into the scheduler. Retain TIMER devices as a separate wrapper
in timer.c/.h. Inline wrappers are currently provided for all timer
operations; a future update will bulk clean these up.
Rather than using macros which hide generation of a string-ified name
for callback functions, the new methods require passing both a function
pointer plus a name string. A new macro FUNC() can be used to output
both, and another macro MFUNC() can be used to output a stub-wrapped
class member as a callback.
Also added a time() method on the machine, so that machine->time() gives
the current emulated time. A wrapper for timer_get_time is currently
provided but will be bulk replaced in the future.
For this update, convert all classic timer_alloc, timer_set,
timer_pulse, and timer_call_after_resynch calls into method calls on
the scheduler.
For new device timers, added methods to the device_t class that make
creating and managing these much simpler. Modern devices were updated
to use these.
Here are the regexes used; some manual cleanup (compiler-caught) will
be needed since regex doesn't handle nested parentheses cleanly
1. Convert timer_call_after_resynch calls
timer_call_after_resynch( *)\(( *)([^,;]+), *([^,;]+), *([^,;]+), *([^);]+)\)
\3->scheduler().synchronize\1\(\2FUNC(\6), \5, \4\)
2. Clean up trailing 0, NULL parameters
(synchronize[^;]+), 0, NULL\)
\1)
3. Clean up trailing NULL parameters
(synchronize[^;]+), NULL\)
\1)
4. Clean up completely empty parameter lists
synchronize\(FUNC\(NULL\)\)
synchronize()
5. Convert timer_set calls
timer_set( *)\(( *)([^,;]+), *([^,;]+), *([^,;]+), *([^,;]+), *([^);]+)\)
\3->scheduler().timer_set\1\(\2\4, FUNC(\7), \6, \5\)
6. Clean up trailing 0, NULL parameters
(timer_set[^;]+), 0, NULL\)
\1)
7. Clean up trailing NULL parameters
(timer_set[^;]+), NULL\)
\1)
8. Convert timer_set calls
timer_pulse( *)\(( *)([^,;]+), *([^,;]+), *([^,;]+), *([^,;]+), *([^);]+)\)
\3->scheduler().timer_pulse\1\(\2\4, FUNC(\7), \6, \5\)
9. Clean up trailing 0, NULL parameters
(timer_pulse[^;]+), 0, NULL\)
\1)
10. Clean up trailing NULL parameters
(timer_pulse[^;]+), NULL\)
\1)
11. Convert timer_alloc calls
timer_alloc( *)\(( *)([^,;]+), *([^,;]+), *([^);]+)\)
\3->scheduler().timer_alloc\1\(\2FUNC(\4), \5\)
12. Clean up trailing NULL parameters
(timer_alloc[^;]+), NULL\)
\1)
13. Clean up trailing 0 parameters
(timer_alloc[^;]+), 0\)
\1)
14. Fix oddities introduced
\&m_machine->scheduler()
m_machine.scheduler()

global functions which are now superceded by the operators and
methods on the class. [Aaron Giles]
Required mappings are:
attotime_make(a,b) => attotime(a,b)
attotime_to_double(t) => t.as_double()
double_to_attotime(d) => attotime::from_double(d)
attotime_to_attoseconds(t) => t.as_attoseconds()
attotime_to_ticks(t,f) => t.as_ticks(f)
ticks_to_attotime(t,f) => attotime::from_ticks(t,f)
attotime_add(a,b) => a + b
attotime_add_attoseconds(a,b) => a + attotime(0, b)
attotime_sub(a,b) => a - b
attotime_sub_attoseconds(a,b) => a - attotime(0, b)
attotime_compare(a,b) == 0 => a == b
attotime_compare(a,b) != 0 => a != b
attotime_compare(a,b) < 0 => a < b
attotime_compare(a,b) <= 0 => a <= b
attotime_compare(a,b) > 0 => a > b
attotime_compare(a,b) >= 0 => a >= b
attotime_mul(a,f) => a * f
attotime_div(a,f) => a / f
attotime_min(a,b) => min(a,b)
attotime_max(a,b) => max(a,b)
attotime_is_never(t) => t.is_never()
attotime_string(t,p) => t.as_string(p)
In addition, some existing #defines still exist but will go away:
attotime_zero => attotime::zero
attotime_never => attotime::never
ATTOTIME_IN_SEC(s) => attotime::from_seconds(s)
ATTOTIME_IN_MSEC(m) => attotime::from_msec(m)
ATTOTIME_IN_USEC(u) => attotime::from_usec(u)
ATTOTIME_IN_NSEC(n) => attotime::from_nsec(n)
ATTOTIME_IN_HZ(h) => attotime::from_hz(h)
