Merging r4130, r4131, r4135: Linux AIO related fixes: *) Fixing Linux AIO syscalls return value handling: syscall(2) uses usual libc convention, it returns -1 on error and sets errno. Obsolete _syscall(2) returns negative value of error. *) Fixing Linux AIO initiatialization: AIO operations are disabled if kernel does not support them. Previously worker just exited. *) The "worker_aio_requests" directive. The default value is 32 AIO simultaneous requests per worker. Previously they were hardcoded to 1024, and it was too large, since Linux allocated them early on io_setup(), but not on request itself. So with default value of /proc/sys/fs/aio-max-nr equal to 65536 only 64 worker processes could be run simultaneously. 32 AIO requests are enough for modern disks even if server runs only 1 worker.
