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 "

  $ hg init repo
  $ cd repo

  $ touch foo
  $ hg ci -Am 'add foo'
  adding foo

  $ hg up -C null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

this should be stored as a delta against rev 0

  $ echo foo bar baz > foo
  $ hg ci -Am 'add foo again'
  adding foo
  created new head

  $ hg debugindex foo
