Unregistered CONFLICTS

[Aleksey Cheusov <cheusov%tut.by@localhost>]

distbb I use for bulk builds automatically collects unregistered
CONFLICTS between packages. Example is below.

http://mova.org/~cheusov/pub/pkgsrc-distbb/NetBSD51/HEAD/logs/20120725.2158/META/check_unregistered_CONFLICTS.html

Not that CONFLICTS is a vital part of pkgsrc, but I'd like to explicitly
register most of them.

One of the main source of unregistered conflicts are python modules.
While different pythons can coexist on the system, some modules cannot,
for example py25-vobject-0.8.1cnb1 and py26-vobject-0.8.1cnb1, the share
bin/ics_diff.  The following patch introduces PYCONFLICTS variable. If
package sets it to "yes", additional conflicts are added. Unless anyone
has a better idea, I'd like to commit this patch and set PYCONFLICTS in
appropriate packages.
