* pbuilder-satisfydepends-experimental, Makefile: alternate

implementation of pbuilder-satisfydepends which supports pulling
build-deps with a version on the apt-get command-line; this is derived
from pbuilder-satisfydepends with the following changes:
- Add and use new package_versions() and candidate_version() helpers;
  the former returns all versions of a package available via APT, the
  later APT's candidate version.
- For versionned build-deps, when building the "apt-get install"
  command, try APT's candidate version or all available versions
  available from APT in ascending order (the reverse order of
  apt-cache's output); checkbuilddep_versiondeps() isn't used for this
  part of the process anymore, but it is still used to honor
  build-conflicts.
- Recover from APT errors caused by unsufficient dependencies
  ("libfoo-dev Depends: bar but baz is to be installed") and missing
  dependencies libfoo-dev Depends: bar but it is not going to be
  installed", or simply "libfoo-dev Depends: bar"); this permits
  simply listing build-deps when uploading to experimental; achieved
  by moving the version matching logic in the new
  versioneddep_to_aptcmd() helper.
* pbuilderrc, pbuilderrc.5: document the availability of the alternate
implementation.
