Create new devices buffered_spriteram<n>_device, which manage buffered

spriteram. Removed core support for legacy buffered spriteram, and
updated all drivers to use the new devices instead. [Aaron Giles]

Removed required/optional_shared_size helpers. Instead the existing
required/optional_shared_ptr helpers now have a bytes() method that
can be used to query the size of the shared region. [Aaron Giles]

-    GENERIC SPRITE BUFFERING
-***************************************************************************/
-
-/* Mish:  171099
-
-    'Buffered spriteram' is where the graphics hardware draws the sprites
-from private ram that the main CPU cannot access.  The main CPU typically
-prepares sprites for the next frame in it's own sprite ram as the graphics
-hardware renders sprites for the current frame from private ram.  Main CPU
-sprite ram is usually copied across to private ram by setting some flag
-in the VBL interrupt routine.
-
-    The reason for this is to avoid sprite flicker or lag - if a game
-is unable to prepare sprite ram within a frame (for example, lots of sprites
-on screen) then it doesn't trigger the buffering hardware - instead the
-graphics hardware will use the sprites from the last frame. An example is
-Dark Seal - the buffer flag is only written to if the CPU is idle at the time
-of the VBL interrupt.  If the buffering is not emulated the sprites flicker
-at busy scenes.
-
-    Some games seem to use buffering because of hardware constraints -
-Capcom games (Cps1, Last Duel, etc) render spriteram _1 frame ahead_ and
-buffer this spriteram at the end of a frame, so the _next_ frame must be drawn
-from the buffer.  Presumably the graphics hardware and the main cpu cannot
-share the same spriteram for whatever reason.
-
-    Sprite buffering & Mame:
-
-    To use sprite buffering in a driver use VIDEO_BUFFERS_SPRITERAM in the
-machine driver.  This will automatically create an area for buffered spriteram
-equal to the size of normal spriteram.
-
-    Spriteram size _must_ be declared in the memory map:
-
-    AM_RANGE(0x120000, 0x1207ff) AM_RAMBANK("sprites") AM_BASE_SIZE_GENERIC(spriteram)
-
-    Then the video driver must draw the sprites from the buffered_spriteram
-pointer.  The function buffer_spriteram_w() is used to simulate hardware
-which buffers the spriteram from a memory location write.  The function
-buffer_spriteram(UINT8 *ptr, int length) can be used where
-more control is needed over what is buffered.
-
-    For examples see darkseal.c, contra.c, lastduel.c, bionicc.c etc.
