Most important thing to note about this change:
ALL DRIVERS MUST NOW EXPLICITLY DECLARE THEIR SCREENS.
Read on for more detail....
Added device tag as a parameter to the start function for devices.
Updated MC6845 to accept this tag.
Added new functions for iterating through the device list and
counting devices of a given type. Updated search and iteration
functions to accept DEVICE_TYPE_WILDCARD to work across all
devices.
Added new macro MDRV_DEVICE_CONFIG_DATA() which is used to set a
single item in an inline data structure.
Removed the per-screen palette_base. This was an idea that never
really worked out, nor have we really needed it.
Defined a new device type VIDEO_SCREEN. Currently this has no
live functionality, but merely serves as a placeholder/identifier
for video screens. Eventually some of the screen management code
may move into the start/stop/reset functions.
Changed MDRV_SCREEN_* macros to build up VIDEO_SCREEN devices
rather than storing values in the screen[] array.
Changed MDRV_SCREEN_ADD to specify a screen type (RASTER, VECTOR,
LCD for the moment).
Removed the older VIDEO_TYPE_RASTER and VIDEO_TYPE_VECTOR; this
information is now determined by walking the screen list.
Removed the screen[] array from machine_config. Modified all code
referencing Machine->config->screen[] and changed it to iterate
over the devices using the new video_screen_first() and
video_screen_next() functions.
(The next step will be to add video_* functions that accept a tag
instead of screen index, and then move systems over to always
referencing screens by tag instead of index.)
Removed implicit screen #0. This means that ALL DRIVERS MUST
EXPLICITLY DECLARE THEIR SCREENS. Updated all drivers to do
so. While there, grouped all MDRV_SCREEN_* parameters together.
Also removed unnecessary VIDEO_TYPE_RASTER and VIDEO_TYPE_VECTOR.
Also removed VBLANK and bitmap format information from vector
games. This was painful and very tedious.
Changed game information to display info about all screens.
