37661fd2ee Fix 32 bit NEON version of DXT1 compression. 
This reverts commit b32e8fa24e.

Apparently it is possible to receive non-uniform data in alpha channel, which
breaks the original assumption about not needing the mask. This seemed to be a
problem only on 32 bit NEON implementation of DXT1 compression. Other
implementations handle such data without degradation of visual output.

7a6564feae Only recycle producers, if there's no data in queue. 
("The queue" is per-thread partial queue here.)

This fixes a problem where one thread writes to the queue, then is
terminated, making the (partially filled) queue available for other
threads to recycle. If another thread re-owns the queue, it will change
the associated thread id, while part of the queue was filled by the
original thread. This obviously created invalid data during dequeue.

The fix makes the recycling process check not only for queue inactivity
(which is marked when the original thread terminates), but also if the
queue is empty, preventing mixing data from different threads.

5fbb811f5d Degrade ARM timer to monotonic raw clock. 
The monotonic raw clock has the same accuracy as reading cntvct registers, but
using clock_gettime() has a measurable impact on queueing time (135 us vs
83 us).

This change is needed to enable ftrace time readings on ARM linux, which
doesn't provide any way to get raw cntvct readings, like x86-tsc on x86.

12969ee497 Track thread context. 
This change exploits the fact that events are processed in batches
originating from a single thread. A single message changing thread
context is enough to handle multiple messages, as opposed to inclusion
of thread identifier in each message.
