GitRepository: allow repo inititialization from subdir

This allows initialization of a GitRepository object, even if the
current working directory (or path given to GitRepository) is not the
top level directory of the git repository.

Don't guess the git meta data dir, but, take it as reported by git
itself.

GitRepository: rewrite git_archive()

Add support for filtering. That is, allow the caller to pipe the output
of git-archive through a filter command, usually a compression program.

Don't use of the deprecated _git_getoutput() method. And don't try
to use _git_inout() either, as we're not interested in the output
(stdout) of git-archive, but, merely want redirect it to a file or pipe
to a filter command.

Also, gets rid of the hackish use of 'cwd' option.

The 'output' is now considered to be relative to the caller's cwd, not
the git repo dir. This should be more intuitive.

buildpackage/git_archive_single() use GitRepository.archive()

Use GitRepository.archive() method like git_archive_submodules() does.
This makes it possible to call git_archive_single() independent of the
callers current working directory.

Get rid of the pipe in git_archive_single() and utilize the filter
command in archive() method of GitRepository, instead.

Move get_compression() out of pkg.PkgPolicy class

Renames the function to parse_archive_filename() and changes it's
return values. Filename parsing is merely generic functionality, not
tied to any packaging policy.

The function now returns the base name of the file (that is, filename
without, archive and compression extensions), archive format and
compression method. Adds supported archive formats 'tar' and 'zip' and
file extension aliases, e.g. 'tgz'.

Add support for changing the prefix directory inside the tarball that is
