Remove # $FreeBSD$ from Makefiles.

Extend expiration of ports broken with -fno-common

Extend the expiration of unmaintained leaf ports that are broken with
-fno-common and previously had a short expiration date.  The new date is set
to 2021-04-01, meaning the ports will be in the 2021Q2 branch, giving people
until 2021-06-30 (10 months from now) to fix issues.
Improve the wording of the deprecation message, mentioning both llvm 11 and
-fno-common.
Bump portrevision to force reinstall.  This way the warning message about
deprecation will be displayed to users installing or reinstalling the
software.

converters/: Fix build with clang11 and deprecate ports@ ports

Remove libexpat.so.6 compatibility link that was added in r374303 to
prevent massive PORTREVISION bumps.  Bump dependent ports that have not
been bumped since.

- Fix trailing whitespace in pkg-descrs, categories [a-f]*

Approved by:	portmgr blanket

Remove ${PORTSDIR}/ from dependencies, Mk and categories a, b, and c.

Fix properties on pkg-plist

In preparation for making libtool generate libraries with a sane name, fix all
LIB_DEPENDS in converters

- Remove NO_STAGE as these have been tested to be safe

With hat:	portmgr

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

Style: tab -> space.

Most contributors copy an existing port when writing their own so reduce the
number of bad examples in the tree.

Repeated words are are hard to to find sometimes.

- Get Rid MD5 support

For ports maintained by ports@FreeBSD.org, remove names and/or
e-mail addresses from the pkg-descr file that could reasonably
be mistaken for maintainer contact information in order to avoid
confusion on the part of users looking for support. As a pleasant
side effect this also avoids confusion and/or frustration for people
who are no longer maintaining those ports.

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

Reset inactive maintainer who has not responded to email.

Chase IETF draft version while i'm here

At Kris's request, back out the MACHINE_ARCH spelling correction until
after 5.4-RELEASE.

Assist getting more ports working on AMD64 by obeying the
Ports Collection documentation and use 'ARCH' rather than 'MACHINE_ARCH'.

o Bump $LIB_DEPENDS line to chase expat's shlib version.
o Bump $PORTREVISION.
