* Add function get_control_re() to pbuilder-satisfydepends-funcs to extract the

  value of source headers from a control file.
* Add function filter_arch_deps() to pbuilder-satisfydepends-aptitude to
  filter out arch dependencies not for a certain arch.
* Source pbuilder-satisfydepends-funcs in pbuilder-satisfydepends-aptitude.
* Add support for arch specific build-deps and build-conflicts to
  pbuilder-satisfydepends-aptitude.
