templatefilters: make json filter handle multibyte characters correctly

It aims to fix javascript error of hgweb's graph view in Japanese 'cp932'
encoding.

'cp932' contains multibyte characters ending with '\x5c' (backslash),
e.g. '\x94\x5c' for Japanese Kanji 'Noh'.
Due to json filter escapes '\' to '\\', multibyte string ending with
'\x5c' is translated to "xxx\", resulting javascript parse error on
a web browser.

This patch changes json() to pass unicode to jsonescape().

Unicode decoding error handler changed to 'replace' by Patrick Mézard.

#!/bin/sh
# This tests if hgweb and hgwebdir still work if the REQUEST_URI variable is
# no longer passed with the request. Instead, SCRIPT_NAME and PATH_INFO
# should be used from d74fc8dec2b4 onward to route the request.
