mesa/x86: fix a typos in SSE4.1 detection

Commit a2fb71e23 introduced 32-bit code for SSE4.1. Fix compilation, and
make sure to check ecx for the SSE4.1 bit.

i965: Use WE_all for FB write header setup on Broadwell.

I forgot to disable writemasking on the OR and MOV which set the render
target index and "source 0 alpha present to render target" bit.

Using get_element_ud is equivalent and avoids a line-wrap.

i965: Listen to BRW_NEW_FRAGMENT_PROGRAM for 3DSTATE_PS_BLEND.

brw_color_buffer_write_enabled depends on brw->fragment_program, which
means we have to listen to BRW_NEW_FRAGMENT_PROGRAM.

On most generations, this was only called from a function that already
subscribed.  However, on Broadwell, we failed to listen to the necessary
event in the atom that emits 3DSTATE_PS_BLEND.

Fix build for darwin

Fix build for darwin, when ./configured --disable-driglx-direct

- darwin ld doesn't support -Bsymbolic or --version-script, so check if ld
supports those options before using them
- define GLX_ALIAS_UNSUPPORTED as config/darwin used to, as aliasing of non-weak
symbols isn't supported
- default to -with-dri-drivers=swrast

v2:
Use -Wl,-Bsymbolic, as before, not -Bsymbolic
Test that ld --version-script works, rather than just looking for it in ld --help
Don't use -Wl,--no-undefined on darwin, either

Make DRI dependencies and build depend on the target

- Don't require xcb-dri[23] etc. if we aren't building for a target with DRM, as
we won't be using dri[23]

- Enable a more fine-grained control of what DRI code is built, so that a libGL
using direct swrast can be built on targets which don't have DRM.

The HAVE_DRI automake conditional is retired in favour of a number of other
conditionals:

HAVE_DRI2 enables building of code using the DRI2 interface (and possibly DRI3
with HAVE_DRI3)

HAVE_DRISW enables building of DRI swrast

HAVE_DRICOMMON enables building of target-independent DRI code, and also enables
some makefile cases where a more detailled decision is made at a lower level.

HAVE_APPLEDRI enables building of an Apple-specific direct rendering interface,
still which requires additional fixing up to build properly.

v2:
Place xfont.c and drisw_glx.c into correct categories.
Update 'make check' as well

Fix build of appleglx

Define GLX_USE_APPLEGL, as config/darwin used to, to turn on specific code to
use the applegl direct renderer

Convert src/glx/apple/Makefile to automake

Since the applegl libGL is now built by linking libappleglx into libGL, rather
than by linking selected files into a special libGL:

- Remove duplicate code in apple/glxreply.c and apple/apple_glx.c.  This makes
apple/glxreply.c empty, so remove it

- Some indirect rendering code is already guarded by !GLX_USE_APPLEGL, but we
need to add those guards to indirect_glx.c, indirect_init.c (via it's
generator), render2.c and vertarr.c so they don't generate anything

Fix and update various includes

glapi_gentable.c (which is only used on darwin), should be included in shared
glapi as well, to provide _glapi_create_table_from_handle()

Note that neither swrast nor indirect is supported in the APPLEGL path at the
moment, which makes things more complex than they need to be.  More untangling
is needed to allow that

i965: Properly return *RESET* status in glGetGraphicsResetStatusARB

The glGetGraphicsResetStatusARB from ARB_robustness extension always
returns GUILTY_CONTEXT_RESET_ARB and never returns NO_ERROR for guilty
context with LOSE_CONTEXT_ON_RESET_ARB strategy.  This is because Mesa
returns GUILTY_CONTEXT_RESET_ARB if batch_active !=0 whereas kernel
driver never reset batch_active and this variable always > 0 for guilty
context.  The same behaviour also can be observed for batch_pending and
INNOCENT_CONTEXT_RESET_ARB.

But ARB_robustness spec says:

  If a reset status other than NO_ERROR is returned and subsequent calls
  return NO_ERROR, the context reset was encountered and completed. If a
  reset status is repeatedly returned, the context may be in the process
  of resetting.

  8. How should the application react to a reset context event?
  RESOLVED: For this extension, the application is expected to query the
  reset status until NO_ERROR is returned. If a reset is encountered, at
  least one *RESET* status will be returned. Once NO_ERROR is
  encountered, the application can safely destroy the old context and
  create a new one.

The main problem is the context may be in the process of resetting and
in this case a reset status should be repeatedly returned.  But looks
like the kernel driver returns nonzero active/pending only if the
context reset has already been encountered and completed.  For this
reason the *RESET* status cannot be repeatedly returned and should be
returned only once.

The reset_count and brw->reset_count variables can be used to control
that glGetGraphicsResetStatusARB returns *RESET* status only once for
each context.  Note the i915 triggers reset_count twice which allows to
return correct reset count immediately after active/pending have been
incremented.

v2 (idr): Trivial reformatting of comments.
