Update CONFLICTS definitions in categories a* to c*

Update the CONFLICTS definitions of ports in the following categories:

- accessibility
- archivers
- audio
- benchmarks
- biology
- cad
- chinese
- comms
- converters

An attempt has been made to use generic conflicts patterns that do not
have to be updated whenever a new version of a conflicting port is
added to the ports system.

There is a misunderstanding that the port being built/installed has to
be omitted from the conflicts pattern. This is not true - the port
being built is implicitly non-conflicting due to logic in bsd.port.mk.

Fix CONFLICTS entries of multiple ports

There have been lots of missing CONFLICTS_INSTALL entries, either
because conflicting ports were added without updating existing ports,
due to name changes of generated packages, due to mis-understanding
the format and semantics of the conflicts entries, or just due to
typoes in package names.

This patch is the result of a comparison of all files contained in
the official packages with each other. This comparison was based on
packages built with default options and may therefore have missed
further conflicts with optionally installed files.

Where possible, version numbers in conflicts entries have been
generalized, some times taking advantage of the fact that a port

Remove # $FreeBSD$ from Makefiles.

Fix dependency detection

Make fonts repecting XDG

Xorg is now looking in ${LOCALBASE}/share/fonts by default
Xorg now accepts symlinks in etc/X11/fontpath.d (as decribed in Xserver(1))
Large cleanup on lots of font ports
All fonts are now properly dynamically generating fonts.dir and fonts.scale
instead of sometime overwriting existing ones)
All fonts are generating fontconfig's cache
Improve consistency in fonts ports

Master port has been stage, add stage support here too so that the man page
is correctly handled

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

Convert Makefile headers to the new format.

Unbreak after upgrade to 0.9.6.

If you ever wonder how to test this (like I did), just do:

  Eterm --mencoding big5 --mfont
"-kc-fixed-medium-r-normal--16-160-72-72-c-160-big5-0"

then cat a Big5 encoded file.

Adopt port.

- Remove unneeded dependency from gtk12/gtk20 [1]
- Remove USE_XLIB/USE_X_PREFIX/USE_XPM in favor of USE_XORG
- Remove X11BASE support in favor of LOCALBASE or PREFIX
- Use USE_LDCONFIG instead of INSTALLS_SHLIB
- Remove unneeded USE_GCC 3.4+

Unbreak: USE_AUTOCONF no longer necessary and it was reverting the LIBTOOL-patch

BROKEN: Incomplete pkg-plist

Whoa there, boy, that's a mighty big commit y'all have there...

Begin autotools sanitization sequence by requiring ports to explicitly
specify which version of {libtool,autoconf,automake} they need, erasing
the concept of a "system default".

For ports-in-waiting:

        USE_LIBTOOL=YES         ->      USE_LIBTOOL_VER=13
        USE_AUTOCONF=YES        ->      USE_AUTOCONF_VER=213
        USE_AUTOMAKE=YES        ->      USE_AUTOMAKE_VER=14

Ports attempting to use the old style system after June 1st 2004 will be
sorely disappointed.

statue@freebsd.sinica.edu.tw has asked for all the maintained
ports to be reset to ports@FreeBSD.org.  We're sorry to see you
go and want to thank you for your help in the past.
