mesa: rewrite accum buffer support
Implemented in terms of renderbuffer mapping/unmapping and format
packing/unpacking functions.
The swrast and state tracker code for implementing accumulation are
unused and will be removed in the next commit.
v2: don't use memcpy() in _mesa_clear_accum_buffer()
v3: don't allocate MAX_WIDTH arrays, be more careful with mapping flags
