Satisfy extension dependency by one of multiple extensions

Hello list,

I have a use case where an extension dependency can be satisfied by one
of five other extensions. Currently I'm unable to express that in the
extension control file, since the elements from 'requires' are currently
searched on exact name match. The attached patch changes this behaviour
for list elements that end with a *, into prefix matching, so that e.g.
table* matches tablefunc.

This allows me to specify in a controlfile

requires 'vocab*'

which is satisfied by having either one of the following extensions loaded:

vocab2005
vocab2006
vocab2008
vocab2009
vocab2010

thoughts?

regards,
Yeb Havinga
