Commit userland part of pf version 3.5 from OpenBSD (OPENBSD_3_5_BASE).

Fix $FreeBSD$ ids.

Fix some style(9) related issues after discussion with/education from bde:
- Add <sys/param.h> and <limits.h> where required (do not depend on other
headers pulling it in).
- __dead -> __dead2
- #if defined() -> #ifdef
- Remove ugly PRIu64 macros and use %llu w/ (unsigned long long) cast.

All changes looped back to OpenBSD (where applicable) for easier sync in the
future.

Apply diff from the port.
Rather small diff for the userland (in contrast to the kernel):
- Some header file location/differences
- Clean compilation on 64bit arch (identified by bento a long time ago)
- ALTQ not (yet) available. Leave a switch for patchsets and future ...
- most files can be used from the vendor branch
