Replace all instances of mapi_table with the actual struct _glapi_table.
The former may have been needed when the OpenVG was around. But since
that one is long gone, there' no point in having the current confusing
mix of the two.

Specifically, move all or most of
glapi/glapi.c to mapi/u_current.c,
glapi/glapi_execmem.c to mapi/u_execmem.c,
glapi/glthread.[ch] to mapi/u_thread.[ch]
and remove their dependencies on core Mesa headers.
