templatefilters: make json filter be byte-transparent (BC) (issue4926)

This is necessary to preserve filename encoding over JSON. Instead, this
patch inserts "|utf8" where non-ascii local-encoding texts can be passed
to "|json".

See also the commit that introduced "utf8" filter.

  $ hg log -T "\\xy" -R a
  hg: parse error: invalid \x escape
  [255]

Set up repository for non-ascii encoding tests:

  $ hg init nonascii
  $ cd nonascii
  $ python <<EOF

json filter should try round-trip conversion to utf-8:

  $ HGENCODING=ascii hg log -T "{branch|json}\n" -r0
  "\u00e9"

json filter should not abort if it can't decode bytes:
(not sure the current behavior is right; we might want to use utf-8b encoding?)

  $ HGENCODING=ascii hg log -T "{'`cat utf-8`'|json}\n" -l1
  "\ufffd\ufffd"

utf8 filter:

  $ HGENCODING=ascii hg log -T "round-trip: {branch|utf8|hex}\n" -r0
  round-trip: c3a9

json filter should escape HTML tags so that the output can be embedded in hgweb:

  $ hg log -T "{'<[e-mail]>'|json}\n" -R a -l1
  "\[e-mail]\u003e"

Set up repository for non-ascii encoding tests:

  $ hg init nonascii
  $ cd nonascii
  $ python <<EOF

json filter should try round-trip conversion to utf-8:

  $ HGENCODING=ascii hg log -T "{branch|json}\n" -r0
  "\u00e9"

json filter takes input as utf-8b:

  $ HGENCODING=ascii hg log -T "{'`cat utf-8`'|json}\n" -l1
  "\u00e9"
  $ HGENCODING=ascii hg log -T "{'`cat latin1`'|json}\n" -l1
  "\udce9"

utf8 filter:

  $ HGENCODING=ascii hg log -T "round-trip: {branch|utf8|hex}\n" -r0
  round-trip: c3a9
