net/gogoc: new patch with various improvements

- When shutdown, the correct behavior is to send SIGHUP.
- New patch patch-icmp_echo_engine.c: When PID of the gogoc process greater
  than 65536, it can not perform timeout ping check correctly, due to
  echo_id in icmp_hdr is declared as uint16_t.
- New patch patch-freebsd.sh: To mute dmesg noise "nd6_dad_timer: cancel
  DAD on tun0 because of ND6_IFF_IFDISABLED."

When there is a do-install target, do not use a post-install target, do
everything at once.  Sometime, rename post-install into a options helper
target.

I did not fix ports that were such a mess that I could not figure out
what they really wanted to do.  I also did not change ports that had
some version of an auto-plist code in post-install, for the same reason.

Convert GMAKE to MAKE_CMD
Please note that lots of invocation of MAKE_CMD here are wrong as they do not
properly respect MAKE_ENV and friends

Add NO_STAGE all over the place in preparation for the staging support (cat:
net)

In the rc.d scripts, change assignments to rcvar to use the
literal name_enable wherever possible, and ${name}_enable
when it's not, to prepare for the demise of set_rcvar().

In cases where I had to hand-edit unusual instances also
modify formatting slightly to be more uniform (and in
some cases, correct). This includes adding some $FreeBSD$
tags, and most importantly moving rcvar= to right after
name= so it's clear that one is derived from the other.

gogoc is gogoCLIENT, which is needed to connect to Freenet6 tunnel.

Freenet6 Tunnel is an IPv6 access service which enables thousands of people
from all over the world to experience the best solution for a smooth and
incremental deployment of IPv6. Freenet6 Tunnel users can get IPv6 connectivity
from anywhere, including from behind any NAT device or from outside of their
home network.

Two similar PRs were sent for the port, take the first one with some
