Khronos recommends that the GLES 3.1 library also be called libGLESv2.
It also requires that functions be statically linkable from that
library.
NOTE: Mesa has supported the EGL_KHR_get_all_proc_addresses extension
since at least Mesa 10.5, so applications targeting Linux should use
eglGetProcAddress to avoid problems running binaries on systems with
older, non-GLES 3.1 libGLESv2 libraries.

This was fixed in revision 47 of the ARB_dsa spec in Oct 22, 2015. Since
it's horrible to have differing APIs across library versions, we should
attempt to minimize the impact by backporting it as far as possible and
hope no one notices.

Coverity complains that the computed sizes can lead to negative lengths
passed to memcpy. If that happens we've been handed invalid arguments
anyway, so just bomb out.
The funky "0%s" is because the size string for the variable-length part
of the request is of the form "+ safe_pad() ...", and a unary + would
coerce the result to always be positive, defeating the overflow check.

GL_KHR_robustness adds the GL_CONTEXT_LOST error and five new entry
points that we already implement. This patch adds a new dispatch table
that returns GL_CONTEXT_LOST from all entry points and implements the
GL_LOSE_CONTEXT_ON_RESET strategy by setting that table when we learn
that we've lost the context.
With the GL_CONTEXT_LOST reporting in place and dispatch for the new
entry points we can turn on GL_KHR_robustness.

Technically, this was introduced with GL 4.4. However, I believe it
was intended to be retroactive. As far as I know, AMD has never
supported primitive restart with patches, while NVidia and Intel do.
This necessitated the need for a query which would allow applications
to figure out whether this was usable or not.
I decided to expose it everywhere ARB_tessellation_shader is exposed.
(It's also in both OES and EXT_tessellation_shader.)
Enable this for i965 and Gallium drivers which expose the capability.

Removes the public symbol _glapi_create_table_from_handle from
libGL.so.1.2.0 on all platforms except Darwin.
Since the symbol is not used on other platforms it makes sense to
build glapi_gentable.c only on Darwin.
As a side effect it accelerates the build a bit and reduces the size
of libGL.so.1.2.0 as follows:
size lib/libGL.so.1.2.0 on my system shows

469211 21848 2720 493779 788d3 lib/libGL.so.1.2.0 before

This patch significantly reduces the size of the libGL.so binary. It does
not change the (externally visible) behavior of libGL.so at all.
gl_gentable.py generates a function, _glapi_create_table_from_handle.
This function allocates a large dispatch table, consisting of 1300 or so
function pointers, and fills this dispatch table by doing symbol lookups
on a given shared library. Previously, gl_gentable.py would generate a
single, very large _glapi_create_table_from_handle function, with a short
cluster of lines for each entry point (function). The idiom it generates
was a NULL check, a call to snprintf, a call to dlsym / GetProcAddress,
and then a store into the dispatch table. Since this function processes
a large number of entry points, this code is duplicated many times over.
We can encode the same information much more compactly, by using a lookup
table. The previous total size of _glapi_create_table_from_handle on x64
was 125848 bytes. By using a lookup table, the size of
_glapi_create_table_from_handle (and the related lookup tables) is reduced
to 10840 bytes. In other words, this enormous function is reduced by 91%.
The size of the entire libGL.so binary (measured when stripped) itself drops
by 15%.
So the purpose of this change is to reduce the binary size, which frees up
disk space, memory, etc.
