libtasn1 shlib bump fallout

[Jan Henrik Sylvester]

I know that some people do not agree with the PORTREVISION bumping at 
all. Anyhow, after the libtasn1 shlib bump there were some ports bumped, 
but many got missed that have files linking against libtasn1.so.3 
according to 'libchk -v'.

I found these:
cups-pstoraster-8.15.4_2
ekiga-2.0.11_5
ghostscript8-8.63
gnome-control-center-2.24.0.1
gnome-panel-2.24.3
gtk-2.14.7
gvfs-1.0.3
kdelibs-3.5.10
libpurple-2.5.4
pidgin-2.5.4
wireshark-1.0.5

I build these ports with standard options, but not in a tinderbox. Thus, 
I am not really sure if default packages from a tinderbox are affected.

At least some of the ports mentioned above do not have a dependency 
listed, but depend indirectly on libtasn1 installed.

Anyhow, bumping recursively seems to be a little too much, since most 
indirect dependencies do not link directly -- on my system, according to 
'libchk -v' there are many big packages (kde, openoffice.org, 
thunderbird, firefox, ...) unaffected. Thus, there should probably be 
only a note about it in UPDATING.

I am still not sure, if relying on the 'libchk -v' output is any good 
for removing stuff from lib/compat/pkg, but I do not know a better way 
to ensure packages build not depending on old libs.

Cheers,
