[Mesa-dev] [PATCH 07/22] dri/common: Add option to allow exposure of 10 bpc color configs. (v2)

[Mario Kleiner]

Some clients may not like RGB10X2 and RGB10A2 fbconfigs and
visuals. Add a new driconf option 'allow_rgb10_configs' to
allow per application enable/disable.

The option defaults to enabled.

v2: Rename expose_rgb10_configs to allow_rgb10_configs,
    as suggested by Emil. Add comment to option parsing,
    to make sure it stays before the ->InitScreen().
