[PATCH 001/114] Add initial port for Phoenix-RTOS.

[Jakub Sejdak]

So question to Corrina or anyone else who is responsible for
maintenance: what should I do now to have my patches applied? Or are
they already rejected?
If you wish I can send another set with changed/removed license in
each file, but this will generate another huge set of emails.
As for duplicated headers: this shouldn't be much of a problem,
because the same situation is, as I see, already in Linux port.
This has no impact on Cygwin, RTEMS or FreeBSD builds.

Later on, after publishing this (and also patches to binutils & gcc)
we can think about reducing headers duplication.

time_t is currently defined in kernel header as typedef from int.
