Log Message:
Removed obsoletes EMUL_NO_BSD_ASYNCIO_PIPE and EMUL_NO_SIGIO_ON_READ flags.
Async I/O OS specifities should now handled in OS specific code. Linux
has been done, but other emulation should be handled. See case LINUX_F_SETFL
in sys/compat/linux/common/linux_file.c:linux_sys_fcntl() for more details.
