devel/kdesdk, sysutils/kdeadmin: Remove stray dollar sign ('$')

... in the end of DISTVERSION.

Mk/Uses: always use colon for build/run suffix

Most USES use a colon for build/run(/test) suffixes. Change kde.mk,
qt.mk and pyqt.mk to do the same, and update all ports using that.

*: fix tab vs. space issues, and comments according to the guide.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

Update devel/okteta to the latest version.

	https://www.kde.org/applications/utilities/okteta

* Fixed: bad offset of elements in statusbar
* Translations improved (cs, en_GB, ga, lv, nn, pt)

While here, bump consumer devel/kdevelop (also the library names
have changed in innovative ways) and devel/kdesdk (which was still
worried about the KDE4 version of okteta).

Update KDE Applications to 18.12.2

Fix Qt5 symbol version scripts to put the catch-all clause first.  When
a symbol matches multiple clauses the last one takes precedence.  If the
catch-all is last it captures everything.  In the case of Qt5 libraries
this caused all symbols to have a Qt_5 label while some should have
Qt_5_PRIVATE_API.  This only affects lld because GNU ld always gives the
catch-all lowest priority.

Older versions of Qt5Webengine exported some memory allocation symbols from
the bundled Chromium.  Version 5.9 stopped exporting these [1] but the
symbols were kept as weak wrappers for the standard allocation functions to
maintain binary compatibility. [2][3]  The problem is that the call to the
standard function in these weak wrappers is only resolved to the standard
function if there's a call to this standard function in other parts of
Qt5Webengine, because only then is there a non-weak symbol that takes
precedence over the weak one.  If there's no such non-weak symbol the call

Replace bsd.qt.mk by Uses/qt.mk and Uses/qt-dist.mk

From now on, ports that depend on Qt4 will have to set
	USES=		qt:4
	USE_QT=		foo bar
ports depending on Qt5 will use
	USES=		qt:5
	USE_QT=		foo bar

Add the KDE metaports

* add multimedia/dragon (was missing)
* add the meta ports for the categories
* add x11/kde5 [yeah, we know, there technically is no "KDE 5"]

KDE2 is dead. The source is no longer available.

BerkeleyDB cleanup - stage 3
Version 2 of Berkeley DB has been repo-copied to databases/db2, for
naming consistency with the other ports.  Fix dependencies accordingly.

Distfiles have been moved on kde site to Attic.

Fix the KDE ports to not use objprelink, if OSVERSION >= 500029.  This is
not tested other than for syntax, but should DTRT from what I understand
of the problem.

Bring in a few changes to the KDE ports infrastructure, and some fixes.    -
Move all stuff specific to kde core ports to x11/kde2/Makefile.kde.      +
Default to compile optimized for speed, not debugging, in ports        builds,
not just packages.  We don't really get that many backtraces        or debugging
information, and there's a better way to provide these        things to people
willing to spend some time working on KDE.  It's        at (as announced
before): http://freebsd.kde.org/.    - Remove teTeX dependency for kdegraphics2
upon request, and being unable      to find any reason not to.  Apparently,
kdegraphics still compiles      libkdvi and kdvi -- I guess dvips is merely a
runtime dependency.      Therefore to enable its use one just needs to add the
teTeX package.      Bump PORTREVISION to reflect dependency change.    - Fix
koffice port by removing PYTHON_VERSION, which is unnecessary.    

If !WANT_KDE_NDEBUG and !PARALLEL_PACKAGE_BUILDING, also add   --enable-debug
and turn off stripping of binaries so we actually get all   the debugging we're
supposed to get.  :)    

Conditionalize use of objprelink based on whether we're running on  
MACHINE_ARCH=i386 *and* whether NO_KDE_OBJPRELINK is defined.    

Do not include malloc.h    

Fix a problem with auto{conf,make}:  some build magic was introduced to   make
sure that the "autoconf" and "automake" binaries KDE looked for were   found and
were autoconf213 and automake14 (as there are issues with the   latest
versions), but the logic in setting $PATH was wrong.  This puts  
${WRKSRC}/auto-bin before the rest of the users $PATH.  This fixes KDE   auto*
problems if automake14 and automake-1.5 are both installed.    

Upgrade KDE to 2.2.2:    * General:           - Support for objprelink.         
 - Hack for autoconf 2.13/automake 1.4.  Note that we can't use             the
standard USE_AUTO* because they change things in work/*;             KDE has its
own way of doing that.           - Light cleanup of extra dirs in the PLISTs
provided by              my mkplistpkg[1] script.           - Speedups of both
compile and runtime through the usage of             --disable-debug and
--enable-final.  The latter did not work             with the kdemultimedia
package, unfortunately.           - Patch updates.    * audio/kdemultimedia2:   
       - Patch to fix KSCD on FreeBSD[2].  It works very well now.    *
deskutils/kdepim:           - Enable kpilot[3].  Pull in the latest pilot-link
stuff.    * devel/kdesdk,    * devel/kdevelop:           - No specific changes. 
  * devel/qt-designer:           - Make this port depend almost entirely on qt23
to make it more             maintainable, so I don't have to keep hacking the
patches to             get them to apply.    * editors/koffice,    *
games/kdegames,    * graphics/kdegraphics:           - No specific changes.    *
misc/kdeaddons:           - SDL is required now.  Cull SDL PLIST_SUB and such.  
        - Fix breakage from hardcoding "sdl-config".    * misc/kdeutils2:       
   - Fix problem with klaptopdaemon[4] where it didn't properly            
display the battery time.  This patch is untested, but applied.    *
net/kdenetwork2:           - Fix DCC for KSIRC[5].           - Remove ktalkd
from the build.  It requires some weird thing             in the configure
script that I don't have time to look at.    * sysutils/kdeadmin:           - No
specific changes.    * textproc/kdoc:           - Remove bogus requirement that
kdoc requires Perl 5.6.0; it sure             seems to operate fine with >=
5.005.  But I'll let time tell.    * www/quanta:           - No specific changes
(--disable-debug support only).    * x11/kde2:           - No specific changes. 
  * x11/kdebase2:           - Fix ksysguard compile by merging the files from
the HEAD branch             of KDE CVS that were missing at release time for
FreeBSD[6].  :\    * x11/kdelibs2:           - Recognize CUPS' spinoff[7].      
    - Add libxslt dependency since it was removed from kdelibs.           - Fix
libxml compile problems[8] (accomplished by upgrading).           - Remove
libkformula from port Makefile; this library has been             spun off into
koffice.           - Fix mode problems with DCOP[9].  This allows you to save
files             properly.  It also seems to be a FreeBSD specific problem.    
      - Fix bashisms in kdeprint/imagetops script[10].    * x11-clocks/kdetoys2:
          - No specific changes.    * x11-toolkits/qt23:           - Do NOT
upgrade to QT 2.3.2[11].           - Allow devel/qt-designer to depend on this
port entirely for the             patches by adding a perlre to accomplish this.
   * x11-wm/kdeartwork:           - No specific changes.    

Upgrade to 2.2.1.    

Set DIST_SUBDIR=KDE    

MAINTAINER -> kde@FreeBSD.org    

Depend on kdebase rather that kdelibs.    

Upgrade to 2.2    

*sigh*  They changed the path to the tarballs again.  This was verified   on my
local mirror at ftp://csociety-ftp.ecn.purdue.edu/pub/kde/.  :\    

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.    

Update -> 2.1.1.    

Add kdesdk.
