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.
v2: add comments for the accessors
