mesa: re-enable GLX TLS to help i386

mesa's assembly code for i386 only seems to be position independent
when compiled with ELF TLS, so having it disabled causes worse problems
than the edge cases ELF TLS causes.

potentially the assembly code could be fixed (it looks like it not
being safe is a bug), it could also be disabled, but i don't currently
have the means to measure the impact of that.

disable use of ELF TLS in Mesa/libGL

this is an optimization that primarily benefits linux/glibc -
most other systems have this disabled. in netbsd we've tried to
patch around it to make things work

this is an optimization that primarily benefits linux/glibc -
most other systems have this disabled. in netbsd we've tried to
patch around it to make things work, but there still appears to be
some edge cases where libGL mysteriously crashes.

discussed on tech-x11 some time ago. already in place in pkgsrc.

Update build logic for mesa 19.1.7.

A lot of files are now living outside of dist, since they're not in the
distributed sources: they're generated, usually by python/meson.

The remaining changes are due to files being moved around.

except i386, which now suffers from locked atomics because we
don't have clever ifunc tricks in libc.

hopefully not breaking non-x86 clang builds, which
have MKLLVM set.

move hack to build llvm libraries soon enough.

add u_process.c to libGL specifically (dri, gallium and libGL all need
it).

Add some missing includes for pipe-loader when it moved to gallium

shuffle around:

some files move from shared driver.mk/loader.mk into gallium.
others move to shared.

add i915 files.

now i965 glxgears works (amd64).

Adjust for MesaLib 18.

Build llvmpipe driver on x86 (the driver itself is x86-only).
build llvm on all x86, even on GCC builds.
galahad driver removed (upstream).
Don't build mesa 7 at all.

move mesa10 build into .old scheme:

- add ${X11SRCDIR.MesaLib.old} and introduce ${X11SRCDIR.Mesa} as an
alias for either the former or the non old. this allows many of
the makefiles to simply use ${X11SRCDIR.Mesa} (but does not really
enable much sharing of makefiles, but reduces their diffs.)

- use mesa-which.mk to define ${OLD_PREFIX} to either "" or ".old",
and to know if to build 'dri7' (.old only.) ${OLD_PREFIX} is used
by other code (eg, LIBDPLIBS) to pick the right subdir.
