This made for an unfortunately large amount of work since we were using it
fairly heavily internally. However, gl_shader_stage does basically the
same things, so it's not too bad.
Currently it stores strlen(buf) whenever the user originally provided a
negative value for length.
Although I've not seen any explicit text in the spec, CTS requires that
the very same length (be that negative value or not) is returned back on
Pop.
So let's push down the length < 0 checks, tweak the meaning of
gl_debug_message::length and fix GetDebugMessageLog to add and count the
null terminators, as required by the spec.
v2: return correct total length in GetDebugMessageLog
v3: rebase (drop _mesa_shader_debug hunk).

We're about to rework the meaning of gl_debug_message::length to only
store the user provided data. Thus we should add an explicit validation
for null terminated strings.

These new (relative to ARB_debug_output) tokens, have been explicitly
separated from the existing ones in the spec text. With the reference
to glDebugMessageInsert was dropped.
At the same time, further down the spec says:
"The value of <type> must be one of the values from Table 5.4"
... and these two are listed in Table 5.4.
The GL 4.3 and GLES 3.2 do not give any hints on the former
'definition', plus CTS requires that the tokens are valid values for
glDebugMessageInsert.

As per the spec quote:
"All messages are initially enabled unless their assigned severity
is DEBUG_SEVERITY_LOW"
We already had MEDIUM and HIGH set, let's toggle NOTIFICATION as well.

We already have one group (the default) as specified in the spec. So
lets return its size, rather than the index of the current group.

The variable is used as the actual index, rather than the size of the
group stack - rename it to reflect that.

The extension requires (cough implements) GetPointervKHR (alias of
GetPointerv) which in itself is available for ES 1.1 enabled mesa.
Anyone willing to fish around and implement it for ES 1.0 is more than
welcome to revert this commit. Until then lets restrict things.

The KHR_debug extension implements this.
Strictly speaking it could be used with ES 1.0, although as the original
function is available on ES 1.1, I'm inclined to lift the KHR_debug
requirement to ES 1.1.

There are a few legacy OpenGL apps on Windows which need this extension.
We basically use glCopyTex[Sub]Image to implement wglBindTexImageARB (see
the implementation notes for details).
v2: refactor code to use st_copy_framebuffer_to_texture() helper function.

This helper is used by the WGL state tracker to implement the
wglBindTexImageARB() function.
This is basically a new "meta" function. However, we're not putting
it in the src/mesa/drivers/common/ directory because that code is not
linked with gallium-based drivers.
