gcc6 landed in rawhide, and all of a sudden building mesa got very
noisy.  This patchset cleans up most of the warnings (especially
the first one which shows up everywhere that #includes hash_table.h)

There are two remaining:

src/gallium/auxiliary/util/u_debug_stack.c: In function 
‘debug_backtrace_capture’:
src/gallium/auxiliary/util/u_debug_stack.c:108:18: warning: calling 
‘__builtin_frame_address’ with a nonzero argument is unsafe [-Wframe-address]
    frame_pointer = ((const void **)__builtin_frame_address(1));
    ~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Not sure there is anything we *can* do about that one.  And:

  src/gallium/auxiliary/util/u_debug_stack.c: In function 
‘debug_backtrace_capture’:
  src/gallium/auxiliary/util/u_debug_stack.c:108:18: warning: calling 
‘__builtin_frame_address’ with a nonzero argument is unsafe [-Wframe-address]
      frame_pointer = ((const void **)__builtin_frame_address(1));
      ~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Not sure there is anything we *can* do about that one.  And:

  src/mesa/main/get.c:473:18: warning: ‘extra_version_40’ defined but not used 
[-Wunused-const-variable]
   static const int extra_version_40[] = { EXTRA_VERSION_40, EXTRA_END };
                    ^~~~~~~~~~~~~~~~
  src/mesa/main/get.c:232:21: warning: ‘extra_ARB_compute_shader’ defined but 
not used [-Wunused-const-variable]
      static const int extra_##e[] = {  \
                       ^
  src/mesa/main/get.c:441:1: note: in expansion of macro ‘EXTRA_EXT’
   EXTRA_EXT(ARB_compute_shader);
   ^~~~~~~~~

Not really sure what we should do about that one.
