This is the 64-bit unsigned division and remainder from the Linux
kernel, for 32-bit host systems.

The new lib/ directory can be used by archs to pick files, and that's
already exemplified by arch-gnu-linux and arch-bare-linux.

Maybe we should consider some generic lib, as most of this can be
shared across freestanding archs (we must check whether other
freestanding places are really so lib-less os they have these minimal
functions for example from newlib)

These remove style warnings and errors, mostly mine. External files
(such as hw files in arch-spec and syscall stuff in bare-linux) have
not been fixed and should not be, in my opinion.

While the code layout comes from ptp-proposal, this is a different
package, now called pptp for "Portable PTP".

This fixes the "ppi->ch.fd" using the two descriptors
in the new net_path structure. It also istantiates a static
net_patch to avoid malloc in the freestanding environment.

The program is not linking because some functions called by
the protocol are still missing in this architecture.

With new compilers (e.g., Debian 6) the resulting binary
was not starting because there's an extra section before .text

Patch coming from ptp-proposal (author: Alessandro Rubini)
Some distributions (e.g: ubuntu-lucid) use the stack protector by
default. This disables it so arch-bare-linux can compile and run.
The option is present at least from gcc-4.2, but 4.0 and ealier ones
are known not to accept it.

code was pruned from specific "ptp-proposal" protocol and the
skeleton of IEEE-1588 states was made. Next step is to insert,
step by step, the structs defined in ptpd. Still something needs
to be removed or renamed, but this should be a fair starting point.
