mesa: overhaul debug namespace support

_mesa_HashTable is not well-suited for us: it locks a mutex unnecessarily and
it does not accept 0 as the key (and have branches to handle 1 specially).
What we really need is a sparse array.  Whether it should be implemented as a
hash table, a list, or a bsearch()-able array requires investigations of the
use models.

We choose to implement it as a list for now, assuming it is common to have a
short list of IDs in each (source, type) namespace.  The code is simpler, and
the memory footprint is lower.  This also fixes several corner cases such as
making messages to have different states at different severities.

mesa: delay copying of debug groups

Do not copy the debug group until it is about to be written.  One likely
scenario of using glPushDebugGroup/glPopDebugGroup is to enclose a sequence of
GL commands and give them a human-readable description.  There is no message
control change in this scenario, and thus no need to copy.

This also reduces the initial size of gl_debug_state from 306KB to 7KB.

mesa: clean up debug output namespace handling

Add functions to provide these operations on a struct gl_debug_namespace:

  init():    initialize the namespace
  copy():    copy all elements from one namespace to another
  clear():   clear all elements (to free the memories)
  set():     set the value of an element
  set_all(): set the value of all elements
  get():     get the value of an element

A debug namespace is like a sparse array.  The length of the array is huge,
2^sizeof(GLuint), but most of the elements assume the same value sepcified by
set_all().

mesa: use accessors for struct gl_debug_state

When GL_DEBUG_OUTPUT_SYNCHRONOUS is GL_TRUE, drivers are allowed to log debug
messages from other threads.  That requires gl_debug_state to be protected by
a mutex, even when it is a context state.  While we do not spawn threads in
Mesa yet, this commit makes it easier to do when we want to.

Since the definition of struct gl_debug_state is no longer needed by the rest
of the driver, move it to main/errors.c.  This should make it even harder to
use the struct incorrectly.
