[PATCH 2/3] gitsm.py: Add support for alternative URL formats from submodule files

[Mark Hatle <mark.hatle@windriver.com>]

The following appear to be the git supported formats:

  proto://user:pass@host/path  (URI format)
  user@host:path (SSH format)
  /path or ./path or ../path (local file format)

We adjust the parsing to find out if we have a URI format or not.
When we are NOT in URI format, we do our best to determine SSH or
file format by looking for a ':' in the overall string.  If we find
a ':' we assume SSH format and adjust accordingly.

Note, in SSH format we simply replace the ':' with a '/' when constructing
the URL.  However, if the original path was ":/...", we don't want '//' so
we deal with this corner case as well.
