MESA_FORMAT_LnAn_* puts the luminance in the low part of the integer and

This series fixes gallium to be consistent with that layout on big-endian.
Following the convention established last year, PIPE_FORMAT_LAnn and
PIPE_FORMAT_RGnn are the equivalent gallium formats. Where defined,
PIPE_FORMAT_LnAn puts the luminance first in memory and the alpha
last in memory.
Patch 1 also fixes an endianness bug in mesa swrast for MESA_FORMAT_L8A8_SRGB.
AFAICT all other L/A and R/G formats are handled correctly.
v2, with subject lines fixed to include the "component:" bit. No code changes
from v1.
Richard Sandiford (5):
swrast: Fix handling of MESA_FORMAT_L8A8_SRGB for big-endian
util: Add PIPE_FORMAT_AnLn and PIPE_FORMAT_GnRn formats
util: Define PIPE_FORMAT_{LA,AL,RG,GR}nn aliases
mesa: Add MESA_FORMAT_A8L8_{SNORM,SRGB}
st/mesa: Fix handling of LA and RG formats for big-endian
This series looks good to me.
