Merge security/uvscan-dat into security/uvscan. The uvscan-dat package is

out-of-date very frequently, and it's sole purpose seems to be to provide
the uvscan package with the update_dat script so that uvscan can keep
up-to-date with the latest virus definitions.

A MESSAGE file has been added to security/uvscan that recommends running
"update_dat" to update the virus definitions database to the most recent
version after installation.  The update_dat script has also been rewritten
to allow the new syntax "update -f <DATFILE>" to update from an already-
downloaded DATFILE, so users will still be able to do bulk downloads to
removable media on a machine with a fat connection and be able to compile
and install a usable uvscan package on another machine.

Bump the PKGREVISION on uvscan to 1 and mark the CONFLICT with the obsolete
uvscan-dat packages.
