mesa: Add core support for the GL_AMD_performance_monitor extension.
This provides an interface for applications (and OpenGL-based tools) to
access GPU performance counters. Since the exact performance counters
available vary between vendors and hardware generations, the extension
provides an API the application can use to get the names, types, and
minimum/maximum values of all available counters. Counters are also
organized into groups.
Applications create "performance monitor" objects, select the counters
they want to track, and Begin/End monitoring, much like OpenGL's query
API. Multiple monitors can be in flight simultaneously.
v2: Pass ctx to all driver hooks (suggested by Christoph), and attempt
to fix overallocation of bitsets (caught by Christoph). Incomplete.
v3: Significantly rework core data structures. Store counters in groups
rather than in a global list. Use their array index in the group's
counter list as the ID rather than trying to store a globally unique
counter ID. Use bitsets for active counters within a group, and
also track which groups are active so that's easy to query.
v4: Remove _mesa_ prefix on static functions; detect out of memory
conditions in new_performance_monitor(); make BeginPerfMonitor hook
return a boolean rather than setting m->Active or raising an error.
Switch to GLuint/unsigned for NumGroups, NumCounters, and
MaxActiveCounters (which also means switching a bunch of temporary
variable types). All suggested by Brian Paul. Also, remove
commented out code at the bottom of the block. Finally, fix the
dispatch sanity test (noticed by Ian Romanick).
