Added support for shell (and csh as well) patterns for required

dependencies, as specified in blueprint "improved-version-matching".

It's possible now to require greater, greater or equal than,
less, less or equal than, and equal pkg versions, as well as using
'{}' and '[^!]' csh patterns in dependencies.

Code lifted from FreeBSD, thanks! :-)

Change XBPS_RELVER to 20091107 to match latest additions.
