Let USES=localbase add -L${LOCALBASE}/lib to LIBS instead of LDFLAGS.
USES=localbase:ldflags can be used to set LDFLAGS.  Normally LDFLAGS
appears too early on the command line causing some ports to link with
their own libraries in LOCALBASE (if installed) instead of WRKSRC.

Also make use of _USES_POST so -L${LOCALBASE}/lib is added as late as
possible after anything a port Makefile might set.  Use _USES_POST
instead of .include in libedit.mk and libarchive.mk so things like
'USES=libedit localbase:ldflags' work correctly.

Fix some issues with LIBS in some ports.

Switch ports that don't support LIBS to localbase:ldflags.

Convert to USES=libarchive, reduce over linking

Support stage.

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

- Add LDFLAGS to CONFIGURE_ENV and MAKE_ENV (as it was done with LDFLAGS)
- Fix all ports that add {CPP,LD}FLAGS to *_ENV to modify flags instead

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.

- Unbreak on -CURRENT.

Reset jylefort's port maintainerships.  portmgr has taken his commit bit
into safekeeping due to inactivity.

- Remove USE_GETOPT_LONG which is a no-op since March 2007

- Remove the DESTDIR modifications from individual ports as we have a new,
  fully chrooted DESTDIR, which does not need such any more.
