Subject: gallium: proper constructor and destructor for tgsi_exec_machine

Centralize the creation, initialization and destruction of this struct.
Use align_malloc instead of home-brew alternatives.

Subject: tgsi: make function call code in tgsi_sse.c less opaque

Explictly pass src and dst arguments (previously dst argument was also
being used as a src).  Separate argument handling from the rest of
the function call emit.

Subject: tgsi: simplify and fix sse KIL implementation

Use sse_movmskps to extract the correct bits of the comparison result
for use in updating the killmask.  Simplify some logic around
identifying the set of necessary comparisons to make.

Subject: texenv: Calculate whether we need to do secondary color on our own.

The _TriangleCaps bit is deprecated, not updated when we require, and
is set based on state that hasn't been updated at that point in
_mesa_update_state_locked().

Fixes incorrect clear color in glsl/twoside.c with meta_clear_tris.

Only INLINE (from mesa/main/compiler.h) is defined now.  It may be used
to deal with symbol visibility and int/pointer conversion in the future.

Subject: egl: Support per-thread info.

This commit introduces a "current" system to manage per-thread info.  It
uses TLS, if GLX_USE_TLS is defined, or pthread, if PTHREADS is defined.
If none of them are defined, it uses a dummy implementation that is just
like before.

EGL allows multiple current contexts, as long as they are bound to
different client APIs.

Subject: egl: Add funtions to link contexts and surfaces to displays.

EGL contexts and surfaces are resources of displays.  They should be
managed by displays.  This commit adds a bunch of functions to
egldisplay.c to help establish the links between contexts/surfaces and
displays.  How links are established is considered opaque outside
display.  Functions like _eglGetSurfaceHandle or _eglLookupSurface are
therefore moved to egldisplay.c, with some small modifications.

The idea is also extended to display.  That is, displays need to link to
themselves to be looked up.

This commit only adds the functions.  A commit to use them should
follow.

From cca31340b5a9c0b941946753a31236c7201ca87c Mon Sep 17 00:00:00 2001
From: Chia-I Wu <olvaffe@gmail.com>
Date: Fri, 17 Jul 2009 11:53:03 -0600
Subject: egl: Use the link functions to manage resources.

This commit uses the newly introduced link functions to manage EGL
contexts and surfaces.  As a result of this, the API for drivers are
changed.  All drivers are updated for the change.

Subject: egl: Remove redundant DeletePending flag.

A context or surface that is neither linked to a display nor current to
a thread should be destroyed.  Therefore, an unlinked context or surface
implies a pending delete automatically.
