runtime: improve Linux mutex
...
The implementation is hybrid active/passive spin/blocking mutex.
The design minimizes amount of context switches and futex calls.
The idea is that all critical sections in runtime are intentially
small, so pure blocking mutex behaves badly causing
a lot of context switches, thread parking/unparking and kernel calls.
Note that some synthetic benchmarks become somewhat slower,
that's due to increased contention on other data structures,
it should not affect programs that do any real work.

The RowsPerStrip tag is mandatory according to the spec. However,
Mac OS sometimes (?) omits it. I managed to create such an image

If RowsPerStrip is 0, there was a division by zero in the decoder.
Assume that the image is a single strip in this case.
