* doc/makefile:

  - create doxygen directory to avoid depending on magic (Closes: #628799)
* cmdline/apt-key:
  - explicitly state that net-update is not supported if no url is set
  - require to be root for add, rm, update and net-update
  - clarify update vs. net-update in different distros (Closes: #632043)
* debian/apt.symbols:
  - forgot 'mips' in the list for all architecture dependent symbols
  - comment out gcc-4.5 specific symbols as gcc-4.6 is now default
  - the symbol for PrintStatus() is architecture dependent
* apt-pkg/policy.cc:
  - do not segfault in pinning if a package with this name doesn't exist.
    Thanks to Ferdinand Thommes for the report!
  - Defaults is a vector of Pin not of PkgPin
  - ensure that only the first specific stanza for a package is used
  - save all stanzas which had no effect in Unmatched
  - allow package:architecure in Package:
