1. glthread has a private upload buffer (as struct gl_buffer_object *)
2. the new function glInternalBufferSubDataCopyMESA is used to execute the copy
(the source buffer parameter type is struct gl_buffer_object * as GLintptr)
Now glthread can handle arbitrary glBufferSubData sizes without syncing.
This is a good exercise for uploading data outside of the driver thread.

This commit mainly adds basic infrastructure for tracking vertex array
state.
If glthread gets a non-VBO pointer, this commit delays disabling
glthread until glDraw is called. The next will change that to "sync"
instead of "disable".

for HUD integration in following commits. This valuable profiling data
will allow us to see on the HUD how well glthread is able to utilize
parallelism. This is better than benchmarking, because you can see
exactly what's happening and you don't have to be CPU-bound.
u_threaded_context has the same counters.

This mirrors exactly how u_threaded_context works.
If you understand this, you also understand u_threaded_context.

While a context only has a single glthread, the context itself can be
attached to several threads. Therefore the dispatch table must be
updated in all threads before the destruction of glthread. In others
words, glthread can only be destroyed safely when the context is deleted.
Fixes remaining crashes in the glx-multithread-makecurrent* tests.
V2: (Timothy Arceri) updated gl_API.dtd marshal_fail description.

We want to support glthread on GLES contexts with reasonable apps, and on
desktop for apps that use VBOs but haven't completely moved to core GL.
To do so, we have to deal with the "the user may or may not pass user
pointers to draw calls" problem.

This avoids an extra pointer dereference in the marshalling functions,
which, with the instruction count doing in the low 30s, could actually
matter for main-thread performance.

v2: Keep an allocated buffer around instead of checking for one at the
start of every GL command. Inline the now-small space allocation
function.

before shutdown.
v4: Fix leaks on destroy.
