The ':' character is used as a separator in Open Build Service
and constantly appears in directory names after running osc commands.
Windows do not support ':' as a valid character on file system.
This breaks not only osc but also basic commands such
as 'git clone' on a project that contains colons in paths.
That's why we decided to make osc unsupported on Windows.
The old code does not print any information about the host, for
which the access failed, in case of an URLError. In order to fix
this, add information about the host (and port) to the URLError
instance in core.http_request and use this information in the
babysitter to print out a more detailed error message (which includes
the host (and port)).
For now, we simply add a "private" "_osc_host_port" attribute to
the URLError instance (this way we avoid potential name clashes (due
to the "_osc" prefix) and could come up with a different/more clever
way in the future (due to its privateness)).

Offer a force ("f") choice if, for instance, "osc meta prj foobar -e"
fails due to a HTTPError in metafile.edit. If the force choice is
selected, a new url is constructed by invoking the metafile._URLFactory
instance with a "force='1'" argument (this adds a "force=1" to the
original url's query string (*)) and the corresponding file is PUTed
to the new url. If this PUT fails again and now the "y" choice is
selected, the file is PUTed to the original url (*).
(*): Stricly speaking, from metafile.edit's POV, the concrete url
depends on the passed in metafile._URLFactory instance, though.
Note: the metafile._URLFactory class and its is_force_supported method
is a gross hack. That's why this class is marked as private (that is,
we can remove it at any point in time again without breaking the
API/3rd party applications). An alternative to the metafile._URLFactory
approach would be manual URL parsing and manual URL construction
(adding "force=1" to the query string)... but this is also pretty
awkward (if done properly).

Fixes: #942 ("Offer -f when prjmeta change leads to repo_dependency")
