phobos commit, revision 1692


user: rsinfu

msg:
- Fixed bugzilla 3937: os.path.dirname fails on absolute path.
- Fixed bugzilla 4260: windows & basename.
- Made dirname() tolerant of excess path separators (e.g. "/usr//src").
- Fixed dirname() to deal with Windows' "current directory of a drive" case (e.g. "C:.").
- Made basename() more generic.
- Added more unittests for dirname() and basename().
- Changed version(Win32) to version(Windows) as the module doesn't depend on pointer size.
- Added guard assertion for unknown platforms.
