mesa,gallium,egl,mapi: One definition of C99 inline/__func__ to rule them all.

This is a squash-commit of the two commits listed below.  The first
introduced a 'make check' failure, and the second fixed it.

    mesa,gallium,egl,mapi: One definition of C99 inline/__func__ to rule them all.

    We were in four already...

    NOTE: Candidate for the stable branches.

    Reviewed-by: Brian Paul <[email protected]>
    (cherry picked from commit 70fe7c6d3e1c7534f6598c4616bebf672f42668b)

And:

    tests: Add $(top_srcdir)/include to AM_CPPFLAGS.

    Fixes this build error with make check.
