templatefilters: add "utf8" to get utf-8 bytes from local-encoding text
This will be applied prior to "|json" filter. This sounds like odd, but it
is necessary to handle local-encoding text as well as raw filename bytes.
Because filenames are bytes in Mercurial and Unix world, {filename|json} should
preserve the original byte sequence, which implies
{x|json} -> '"' toutf8b(x) '"'
On the other hand, most template strings are in local encoding. Because
"|json" filter have to be byte-transparent to filenames, we need something to
annotate an input as a local string, that's what "|utf8" will do.
{x|utf8|json} -> '"' toutf8b(fromlocal(x)) '"'
"|utf8" is an explicit call, so aborts if input bytes can't be converted to
UTF-8.
