[Mesa-dev] [PATCH] osmesa: Fix missing symbols when GLX_INDIRECT_RENDERING is defined.

[Jeremy Huddleston]

When GLX_INDIRECT_RENDERING is defined, some symbols are used in
libglapi.a but are not defined.  Define them through the help of
glapitemp.h.

Please see my previous post for discussion.  This patch fixes the build as discussed in that post, but I'd still like to better understand what is going on here and the underlying reason for why this hack is needed.

Changes originally by Chia-I Wu in 6678f597e7c9ba784c9af0c86cfc6821558bcaa7 and 888429360a30090b9ecd17bfd160a88141195235
