Revert "osmesa: don't try to bundle osmesa.def SConscript"

This reverts commit c07df0f2014636b601cdbaff63214296599b1ad5.

Now that the SCons build is back we need to include the files in the
tarball.

scons: build osmesa swrast and gallium

This patch makes it possible to build classic osmesa/swrast on windows
again. It was removed in commit 69db422218b0264b5b8eef45bd003a2544e9cbd6.
Although there is a gallium version of osmesa now, the swrast version
still has more features lacking in llvmpipe, e.g. anisotropic filtering.

automake: rework the git_sha1.h rule, include in tarball

As we'll need the file in the release tarball, rework the rule so that
the file is regenerated _only_ if we're in a git repository.

With this in place we can build vulkan (anv) from a release tarball.

automake: move the git_sha1.h rule a level up

This way we can reuse the header from other places like -
src/intel/vulkan and src/gallium. Only the former is hooked up atm.

Make sure .gitignore is updated, as well as all the users (the mesa
code does not need any changes).

Also ensure that the file is always created by adding it to the

mesa_glinterop: remove mesa_glinterop typedefs

As is there are two places that do the typedefs - dri_interface.h and
this header. As we cannot include the former in here, just drop the
typedefs and use the struct directly (as needed).

This is required because typedef redefinition is C11 feature which is
not supported on all the versions of GCC used to build mesa.

v2: Kill the typedef alltogether, as per Marek.
