We add Linux-realted comments about the atomicity of
write with respect to file offsets. As of Linux 3.14
the file offset update is atomic. That means that
multiple threads calling the write syscall can not possibly
get the same file offset. Therefore the writes should
not overlap and data should not be lost as is required
by POSIX.
Add Linux-specific comments about the atomicity of write() and
the POSIX requirements.

* manual/llio.texi: Add comments discussing why write() may be
considered MT-unsafe on Linux.
Open file description locks have been merged into the Linux kernel for
v3.15. Add the appropriate command-value definitions and an update to
the manual that describes their usage.
