Remove non staged ports without pending PR from net-im and net-mgmt

Resetting maintainership on ports that have not been staged and without any
pending PR (related to stage)

With hat:	portmgr

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

- adoption of optionsNG framework

Approved by:	portmgr (bapt)

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.

Remove more tags from pkg-descr files fo the form:

- Name
em@i.l

or variations thereof. While I'm here also fix some whitespace and other
formatting errors, including moving WWW: to the last line in the file.

- Get Rid MD5 support

Unbreak on amd64

Feature safe:   yes

Begin the process of deprecating sysutils/rc_subr by
s#. %%RC_SUBR%%#. /etc/rc.subr#

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.

Update CONFIGURE_ARGS for how we pass CONFIGURE_TARGET to configure script.
Specifically, newer autoconf (> 2.13) has different semantic of the
configure target. In short, one should use --build=CONFIGURE_TARGET
instead of CONFIGURE_TARGET directly. Otherwise, you will get a warning
and the old semantic may be removed in later autoconf releases.

To workaround this issue, many ports hack the CONFIGURE_TARGET variable
so that it contains the ``--build='' prefix.

To solve this issue, under the fact that some ports still have
configure script generated by the old autoconf, we use runtime detection
in the do-configure target so that the proper argument can be used.

Changes to Mk/*:
 - Add runtime detection magic in bsd.port.mk

Bump portrevision due to upgrade of devel/gettext.

The affected ports are the ones with gettext as a run-dependency
according to ports/INDEX-7 (5007 of them) and the ones with USE_GETTEXT
in Makefile (29 of them).
