log: add support for setting the color scheme

Implements changeable color schemes in the gbp.log module. Color scheme
is given as a colon-separated list, with one color for each log level:
'<debug_color>:<info_color>:<warning_colro>:<error_color>'. Colors can
be given as an integer number (ANSI terminal color code) or color name
(.e.g 'red').  Missing or empty fields are interpreted as using the
default color for that log level.

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.
This utilizes the new filtering functionality of the _git_inout()
method.

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
function of archive() method of GitRepository, instead.

buildpackage/dump_tree: use GitRepository.archive()

Make dump_tree() utilize the GitRepository.archive() method - similarly
to git_archive_submodules() - instead of ad-hoc Python pipes. This makes
dump_tree() work independent of the callers current working directory.

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'.
