COMMENT typos and surrounding whitespace fixes. A few Makefiles where not
included as they contain Latin-1 characters that break the Phabricator
workflow. Category N.

Python cleanup:
- USE_PYTHON* = 2.X -> USE_PYTHON* = 2
- USE_PYTHON* = 2.X+ -> USE_PYTHON* = yes

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

Convert to new options framework, while here cleanup linknx

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.

1. Convert to proper rc.d scripts for mediaproxy and proxydispatcher
2. Maintains the mediaproxy script as the "master," so the user
experience of 'service mediaproxy <start|stop>' will be the same.
3. Instead of resetting ${WRKSRC}, mv the directory to the more typical
name so that we can use mediaproxy.in instead of mediaproxy.sh.in.

Remove painful examples of foo="", with particular prejudice against
constructions that parse out to [ -z "$foo" ] && foo=""

These are bad examples that get copied and pasted into new code, so the
hope is that with less bad examples there will be less need for me to
bring this up in review.

In a few of these files all that were changed were comments so that next
time I search for these patterns I won't trip on the file for no reason.

In a few places, add $FreeBSD$

No functional changes, so no PORTREVISION bumps

- Get Rid MD5 support

Bump PORTREVISION for ports linking to default libmysqlclient.

- Move over to py25 or above
- While here get rid FreeBSD 6.X and md5 support

- DISTNAME= ${PORTNAME}-${PORTVERSION} is the default and not needed.
