This is a copy of pp_printf, that originated from ppsi's diagnostic
code and is now a separate package, with a few more features.
The upstream repository is git://gitorious.org/rubi/pp-printf.git .

This is a major patch, because header files are renamed, and
the header directory with them. Still, no functional change is there.

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

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.
