Пакет rpm: Информация

- rpmdb: rpmdbInitIterator() handles BuildTime and DistTag.
- lib: rpmErase() prints EVR(D|T) when multiple packages matched.

- Changes in what is considered "newer" by rpm -U  pertaining to disttag
  comparison. (On the whole, to determine which package is "newer", first,
  the EVRs are compared, then the branch prefixes of the disttags if the
  disttags are present, and then the buildtimes.) The comparison of the disttags:
  + (new!) If a disttag contains no + separator (old format), the branch prefix is
    assumed to be empty (and hence "older" than any other branch prefix).
  + (new!) If the branch prefix of a disttag is equal to %_priority_distbranch
    (and it is not empty), then it is "newer" than any other ones.
  + (as before, since 4.0.4-alt101.M80P.5) The branch prefixes of disttags are
    ordered lexicographically.
- (disabled in this release; %if_enabled default_priority_distbranch)
  Give a default value to %_priority_distbranch based on the disttag
  when this package is built (the prefix before +).

- lib/depends.c: make headerMatchesDepFlags() aware of the disttag
  of the header. (This should help to obsolete a specific disttag.)
