st/mesa: improve the guess_and_alloc_texture() heuristic

If GL_BASE_LEVEL==0 and GL_MAX_LEVEL==0 that's a pretty good hint that
there'll be a single mipmap level in the texture.

Google Earth sets the texture's state this way before the first glTexImage
call.  This saves a bit of texture memory.
clover: No need for clover::is_zero() to be a functor.

Simplify is_zero() somewhat, and as a side effect work around a gcc compiler
bug that causes build failure.

i965: Don't flush the batch immediately on EndQuery.

The theory I had when I wrote the code was that you wanted to minimize latency
on your queries because the app was going to ask soon.  Only, it turns out
that everybody batches up their queries and asks for the results later (often
after the next SwapBuffers!), so this was a pessimization.

Until now, I had no workload where it mattered enough to benchmark.  Recently
I started playing some Minecraft, which uses tons of queries to decide whether
to render chunks of the terrain.  For that app, avoiding the flush in the
query-generation loop improves performance 22.7% +/- 4.7% (n=3) on an apitrace
capture of it (confirmed in game by watching the fps meter found by pressing
F3, 15/16 -> 20/21 fps).

i965: Stop flushing the batch on timestamp queries, too.

Given the usecase we have of trying to measure timestamps across individual

_mesa_create_exec_table: de-deprecate GetPointerv.

glGetPointerv was de-deprecated in GL 4.3, because GL 4.3 adds
functionality from KHR_debug and ARB_debug_output, which require
glGetPointerv.

This patch modifies _mesa_create_exec_table() to populate
glGetPointerv in the dispatch table for core contexts.

Technically this is not in compliance with the spec--what we really
ought to do for core contexts is expose glGetPointerv only when a GL
4.3 context is in use or one of the two extensions is present.
However, it seems silly to go to that extra work, since the only
client-visible effect would be for glGetPointerv to raise an
INVALID_OPERATION error instead of an INVALID_ENUM error.  Besides,
the other functions set up by _mesa_create_exec_table() only depend on
the API in use, not on the GL version or extensions supported.

_mesa_create_exec_table: GLES3 fixes.

This patch sets up the dispatch table for the following GLES3
functions when a GLES3 context is in use:

- BeginQuery
- BeginTransformFeedback
- BindSampler
- BindTransformFeedback
- BlitFramebuffer
- ClearBufferfi
- ClearBufferfv
- ClearBufferiv
- ClearBufferuiv
- ClientWaitSync
- CopyBufferSubData
- DeleteQueries
- DeleteSamplers
- DeleteSync
- DeleteTransformFeedbacks
- EndQuery
- EndTransformFeedback
- FenceSync
- FramebufferTextureLayer
- GenQueries
- GenSamplers
- GenTransformFeedbacks
- GetInteger64v
- GetQueryObjectuiv
- GetQueryiv
- GetSamplerParameterfv
- GetSamplerParameteriv
- GetStringi
- GetSynciv
- GetTransformFeedbackVarying
- GetVertexAttribIiv
- GetVertexAttribIuiv
- IsQuery
- IsSampler
- IsSync
- IsTransformFeedback
- PauseTransformFeedback
- RenderbufferStorageMultisample
- ResumeTransformFeedback
- SamplerParameterf
- SamplerParameterfv
- SamplerParameteri
- SamplerParameteriv
- TransformFeedbackVaryings
- VertexAttribIPointer
- WaitSync

And it avoids setting up the dispatch table for these non-GLES3
functions:

- ColorMaski
- GetBooleani_v
- Enablei
- Disablei
- IsEnabledi
- ClearColorIiEXT
- ClearColorIuiEXT
- TextureStorage2DEXT
- TextureStorage3DEXT

_mesa_create_exec_table: GLES1 fixes.  TODO: more.

Currently, _mesa_create_exec_table() (in api_exec.c) is used for all
APIs except GLES1.  In GLES1, _mesa_create_exec_table_es1() (a code
generated function) is used instead.

In principle, this shouldn't be necessary.  It should be possible for
api_exec.c to contain the logic for populating the dispatch table for
all API's.

This patch paves the way for using _mesa_create_exec_table() instead
of _mesa_create_exec_table_es1(), by making _mesa_create_exec_table()
(and the functions it calls) expose the correct subset of desktop GL
functions for GLES1.

Unfortunately, we can't switch over to _mesa_create_exec_table() quite
yet.
