url: refactor util.drop_scheme() and hg.localpath() into url.localpath() This replaces util.drop_scheme() with url.localpath(), using url.url for parsing instead of doing it on its own. The function is moved from util to url to avoid an import cycle. hg.localpath() is removed in favor of using url.localpath(). This provides more consistent behavior between "hg clone" and other commands. To preserve backwards compatibility, URLs like bundle://../foo still refer to ../foo, not /foo. If a URL contains a scheme, percent-encoded entities are decoded. When there's no scheme, all characters are left untouched.

However, it goes a step further and "promotes" Windows-style drive letters from being interpreted as host names to being part of the path. - issue2154: Cannot escape '#' in Mercurial URLs (#1172 in THG) The fragment is still interpreted as a revision or a branch, even in paths to bundles. However, when file: is used, percent-encoded entities are decoded, so file:test%23bundle.hg can refer to test#bundle.hg ond isk.
