urpmf foo used to be looking for foo in both package names and
filenames, and to return all files in the package when the package name
matched. The behaviour changed at some point, restore the old behaviour
(#58313)

  o check usage of -a, -! and the like instead of displaying the ugly
    "Internal error: syntax error ..."

- rename _parse_media() into parse_media() for next commit

  o fix fallback on hdlist when xml-info not found

  o fallback on hdlist when xml-info not found (useful for old distribs)

  o fix --synthesis

  o add special code for --files simple case, it makes urpmf 3x faster for
    this often used case

- urpmf, urpmq:
  o use xml info instead of hdlist when possible
    o "urpmq -l" is faster (3x)
    o "urpmf -l" is slower (1.5x)
    o "urpmf --sourcerpm" is much faster
    o see "xml-info" option in urpmi.cfg(5) to see when those files are downloaded
    o new require: perl module XML::LibXML
- urpmq:
  o use rpm file instead of hdlist/xml-info when file is local
  o use URPM::Package->changelogs (need perl-URPM 3.06)
- urpmi.update, urpmi.addmedia, urpmi.removemedia:
  o drop hdlist support replaced with xml media_info
    (this imply file-deps are correctly handled, see genhdlist2(1))
- urpmi.addmedia
  o new --xml-info option
