Say goodbye to Qt 1.x and all of its dependents.  The one port I found
which probably isn't supposed to be removed is misc/instant-workstation,
which had a dependency on audio/xamp (being removed), so I removed that
dependency and bumped PORTREVISION.  All other ports are real dependents
upon Qt 1.x, including KDE 1.x stuff.

Code in bsd.kde.mk supporting these ports is also removed or adjusted.
Also, some adjustments made to accomodate Qt3/KDE3 ports, which will be
committed Real Soon Now (TM), pending repo-copies.

This commit made in impending view of Qt3/KDE3 entering ports tree.

Use ${ECHO_CMD} instead of ${ECHO} where you mean the echo command;   the ECHO
macro is set to "echo" by default, but it is set to "true" if   make(1) is
invoked with the -s option while ECHO_CMD is always set to   the echo command.  
 

Overhaul QT/KDE support:   - bsd.port.mk update to use bsd.kde.mk for
USE_{QT,KDE}*   - Cleanup corresponding ports for bsd.kde.mk update.   - Fix
bsd.kde.mk: use correct kdelibs dependency, put qt at the bottom,     introduce
QT_NONSTANDARD variable for nonstandard configure setup.   - Update KDE2 to
2.1.1.  Two patches included in x11/kdelibs2 to fix the     proxy authentication
that was broken for 2.1.1.  Remove old patches.   - Potentially fix kdelibs
build for alpha.   - Fix qt-designer 2.3.0 build.   - Ruby stuff left alone
since it looks like black magic to me.  Should     still work w/ compat shims
for older USE_QT[,2] style.  Some others     were also left alone for the same
reason.    

Change PKGDIR from pkg/ to .  Also fix places where ${PKGDIR} is   spelled out
(many of which are ${PKGDIR}/MESSAGE -> ${PKGMESSAGE} type   fixes that
shouldn't have been necessary) and the string "/pkg/"   appear.    

Convert category net to new layout.  

USE_LIBTOOL implies GNU_CONFIGURE, so remove redundant GNU_CONFIGURE lines.    

Teach MASTER_SITES about new MASTER_SITE_SOURCEFORGE.    

Remove some files that aren't installed when the esound port is not already  
installed.
