Currently, the trace API passes the pointers that need to be
patched up via 32 bit integers. Such code will not be 64 bit safe.
This patch sends all pointers in a separate array of pointers
for the fixup calls to read from.

This patch updates the trace information for all glUniform*() calls
to have the right data (the actual uniforms that are passed).
In addition, as soon as a program is linked, information regarding
all the active attributes and uniforms is passed on to the debugger.

Export trace information via abstract Unix Domain Socket (UDS).
This allows tracing of applications without INTERNET permission,
and should be faster as well.

Currently users do not have control over the amount of data
captured during tracing. This patch adds 3 settings that users
can enable/disable at runtime:
- capture framebuffer on eglSwap() calls
- capture framebuffer on glDraw*() calls
- capture texture data passed to glTexImage*() calls
Disabling these options when not needed signficantly decreases
the size of the trace file, and reduces performance overhead for
the running application.
These settings are stored in the per process GLTraceState.
A separate thread listens for commands from the host, and updates
the state based on the user commands.

This patch adds two improvements:
1. Protobuf messages are buffered and sent in chunks.
2. Multiple EGL contexts are handled properly: Corresponding
to each EGLContext, a GLTraceContext with a unique ID is created.
On eglMakeCurrent, the appropriate GLTraceContext is set and is
used while tracing subsequent GL Calls in that thread.

Currently, gltrace always attaches the contents of the currently
bound framebuffer. This patch changes it to attach the contents
of FB0 on eglSwap, and the currently bound framebuffer for the
glDraw* calls.

Currently, the contents of the FrameBuffer are sent by encoding
them as the last argument to the function call. As a result, it is
not possible to know if a message has the framebuffer encoded in it
without looking at the function type.
This patch modifies the protobuf definition to include a separate
optional framebuffer message.

This patch provides a framework for tracing GLES 1.0 and 2.0
functions. It is missing a lot of features, but here are the
things it accomplishes:
- Stop building the glesv2dbg library, and build the
glestrace library instead.
- Replace the hooks for glesv2dbg with the ones for glestrace.
- Add the basics for the trace library. Currently, this
traces all GL functions, but not all required data is
sent for all the functions. As a result, it will not
be possible to reconstruct the entire GL state on the
host side.
The files gltrace.pb.* and gltrace_api.* are both generated
using the tools/genapi.py script.
