Changed freebsd.org to FreeBSD.org as suggested.

Seems good to me.

Fix commit message

Variable names consitency.
Move do_resize=0 out of the if to avoid trying resize. May fail one time instead of always.

Fix logic

Do initialization of variables in main().
Renamed the fuction onsigwinch() into resizeit().
Check if return -1 before doing the next ioctl.

Added KASSERT() requested

Style fix for now

Fixed some style issues. On some files checkstyle9.pl is litterally yelling on
allmost all lines. Sorry to have tried to use same incorrect style of the file.
Added suggested #if defined on ipsec_output.c.

Better suggested way to avoid python bycode files than using rm.

Fixed some suggested changes.

• Fix some style bugs as requested (line too long / space before comment etc...)
• Make structure clearer on line 179 of udp6_usrreq.c
• Remove litteral
• Remove unecessary break

Typo on the filename

Configuration file should be in sample

This port doesn't build on 12.4 poudriere, so mark it as BROKEN.
On 13.2 and 14.0 it is building without any pain, didn't tryed on 15.0
indeed.

Fix Makefile LICENSE_FILE, CONFIGURE_ARGS, and some unnecessary things. Remove also duplicated patch files that should not be here

There are some style bugs in the patch. Could you please run tools/build/checkstyle9.pl on the patch file and fix the problems that it reports? In particular, case statements should be at the same indentation level as the switch, and fixing that will fix some of the complaints about lines being too long.

Removed unused function in sys/netinet6/udp6_usrreq.c, added IPv6
support for SOPT_SET and SOPT_GET in sys/netinet/udp_usrreq.c
