Add support for weak dependencies:

A) use RPMTAG_SUGGESTS and RPMTAG_ENHANCES to store them.

This is different to upstream, which uses RPMSENSE_MISSINGOK
   and RPMTAG_REQUIRES/RPMTAG_PROVIDES instead. I chose different
   tags because I wanted to be compatible. The point is that
   applications that don't know about the new MISSINGOK semantics
   will mis-interpret the provides/requires otherwise, which
   I deemed to risky.

B) use RPMSENSE_STRONG to support a "strong" version, "Recommends"
   instead of "Suggests" and "Supplements" instead of "Enhances".

Needs extcond.diff for query operations.
