External jerasure's w into defines
...
In fact, w=8 looks better than w=32, so it may be changed in the future

Use custom decoding instead of just jerasure_matrix_decode()
...
- Cache the decoding matrix
- Don't do unnecessary erasures->erased conversion during decoding
- Avoid extra memory allocations during decoding
- Don't always reconstruct coding chunks
- Reconstruct chunks one-by-one, without overlapping ranges

Several bug fixes
...
- Do not block flock() requests
- Fix stop_client(0) attempts leading to std::bad_function_call
- Fix degraded writes crashing due to an unset stripes[i].missing (at least with a missing parity device)
- Fix recovery B/W reporting
