subrepos: support remapping of .hgsub source paths Given a .hgsub file containing lib/libfoo = http://server/libfoo the 'lib/libfoo' subrepo will be cloned from 'http://server/libfoo'. This changeset introduces a remapping mechanism whereby the source paths (the right-hand sides) in the .hgsub file can be remapped. This subpaths section [subpaths] http://server = /local will result in the 'lib/libfoo' subrepo being cloned from '/local/libfoo' instead of from 'http://server/libfoo'. The patterns (left-hand sides) are really regular expressions and the replacement strings (right-hand sides) can refer to matched groups using normal backreferences. This can be used for more complicated replacements such as [subpaths] http://server/(.*)-hg/ = http://hg.server/\1/ which replaces 'http://server/foo-hg/' with 'http://hg.server/foo/'. All patterns are applied in the order by which they are listed in the config files.
