Raw Blame History

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.
