fixes up some header files. In particular, I adjusted const char
*DEVTEMPLATE_SOURCE = __FILE__ to const char DEVTEMPLATE_SOURCE[] =
__FILE__ which makes it actually const and saves a little memory.

Updated the fcompress APIs to allow for specifying a compression level.
Removed the concept of state saving tags, which was a hack to get save states
to work with multiple CPU cores. Simplified the state saving system as a
result, performing the operation in a single pass and without allocating
a full blob of memory. Also enabled minimal compression.
appropriate, and to keep all global variables hanging off the
machine structure. Once again, this means all state registration
call sites have been touched:
- state_save_register_global* now takes a machine parameter
- state_save_register_item* now takes a machine parameter
- added new state_save_register_device_item* which now uses
the device name and tag to generate the base name
Extended the fake sound devices to have more populated fields.
Modified sound cores to use tags from the devices and simplified
the start function.
Renumbered CPU and sound get/set info constants to align with
the device constants, and shared values where they were perfectly
aligned.
Set the type field in the fake device_configs for CPU and sound
chips to a get_info stub which calls through to the CPU and sound
specific get_info functions. This means the device_get_info()
functions work for CPU and sound cores, even in their fake state.
Changed device information getters from device_info() to
device_get_info() to match the CPU and sound macros.
state_save_combine_module_and_tag() function in favor of passing
the tag when registering. Revisited all save state item registrations
and changed them to use the tag where appropriate.
is either DEVICE_START_OK or DEVICE_START_MISSING_DEPENDENCY. The latter
should be returned by a device if there is another device it depends on
which hasn't been started yet. Added new flag in the device interface to
indicate whether a device has been started.
Changed laserdisc interface to explicitly specify the screen and sound
devices it should route to. Drivers no longer have to manually call
laserdisc_vsync(). Instead, the laserdisc code connects up to the routed
screen device and works based on that screen's VBLANK timing. Removed
all existing calls to laserdisc_vsync().
Changed laserdisc behavior so that it completes the previous video read
and initiates the next read at the end of VBLANK instead of the beginning.
This gives player logic time during VBLANK to alter the slider position
prior to fetching the next frame.
Added new laserdisc callback for vsync begin and changed the update
callback to be called at the end of VBLANK. Also added functions to set
the slider speed, advance the slider, and directly control the video/
audio squelch. In addition, there is a new status function to get the
slider position in general terms.
Added parameter to the VBLANK callbacks supported in emu/video.c. Updated
all callers to provide a callback value.
Fixed bug that would cause watchpoints to trigger if you had a memory
window open to the watchpoint address.
Further updates to the PR-8210 ROM simulation. Still not quite there but
the system is much better understood now. Added layout to the PR-8210
which displays the state of the front-panel LEDs.
