Remove non staged ports without pending PR from net-p2p, net and news

Reset the 99 ports still listed under sylvio@

Sylvio's last commit was 17 months ago, a full 5 months after all of his
ports could have been reset per policy.  Given the push to complete
staging (48 ports are still unstaged, something like 70+ have already
been staged by other committers) and given that PRs are automatically
assigned but never addressed, it's better just to reset all the ports and
PRs so that it's clear to others that these ports are free to maintain.

Move the rc.d scripts of the form *.sh.in to *.in

Where necessary add $FreeBSD$ to the file

No PORTREVISION bump necessary because this is a no-op

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.

Fix a few "bad example" problems in the rc.d scripts that have been
propogated by copy and paste.

1. Primarily the "empty variable" default assignment, which is mostly
${name}_flags="", but fix a few others as well.
2. Where they are not already documented, add the existence of the _flags
(or other deleted empties) option to the comments, and in some cases add
comments from scratch.
3. Replace things that look like:
prefix=%%PREFIX%%
command=${prefix}/sbin/foo
to just use %%PREFIX%%. In many cases the $prefix variable is only used
once, and in some cases it is not used at all.
4. In a few cases remove ${name}_flags from command_args
5. Remove a long-stale comment about putting the port's rc.d script in
/etc/rc.d (which is no longer necessary).

No PORTREVISION bumps because all of these changes are noops.
