scm: mercurial: escape any filenames by urlescape (#2664, #7064).

In Mercurial, filename is not UTF-8 but byte-string.
So it should be escaped to UTF-8-safe string before parsing as XML document.

NOTE: Mercurial's {|obfuscate} filter cannot be used here, because it treats
filename as encoded by HGENCODING.
