formatter: map -Tjson(...) and -Tcbor(...) to templater

Even though custom JSON output could be generated by using
--config template.json="{dict(...)|json}" ..., doing that is tedious because
of the trailing comma handling.

This patch introduces special syntax for JSON/CBOR formats. -Tjson(...) is
translated to template as if function-style template definition were
supported:

  [templates]
  json(...) = "{dict(...)|json}"
  json(...):docheader = "[\n "
  json(...):docfooter = "\n]\n"
  json(...):separator = ",\n "

   }
  ]


Test JSON style:

  $ hg log -k nosuch -Tjson
  [

    "tags": [],
    "user": "User Name <user@hostname>"
   }
  ]

Other unsupported formatter styles:

  $ hg log -qr . -Tpickle
  abort: "pickle" not in template map
  [255]
  $ hg log -qr . -Tdebug
  abort: "debug" not in template map
  [255]

Error if style not readable:

Unparsable function-style references:

  $ hg log -qr . -T'json(-)'
  hg: parse error at 6: not a prefix: )

For backward compatibility, the following examples are not parsed as
function-style references:

  $ hg log -qr . -T'cbor(rev'
  cbor(rev (no-eol)
  $ hg log -qr . -T'json (rev)'
  json (rev) (no-eol)
  $ hg log -qr . -T'json(x="{rev}")'
  json(x="8") (no-eol)
