formatter: add support for changeset templating
Some formatter-based commands provide fields that are identical to the ones
defined in templatekw, but we had to specify them manually to support all
changeset-based template keywords.
This patch adds fm.context() that populates all templatekw. These keywords
are available only in template output, so we still need to set important
keywords via fm.data() if they should be available in e.g. JSON output.
Currently fm.context() takes only 'ctx' argument. It will eventually be
extended to take 'fctx' to support file-based keywords (e.g. {path}) seen
in hgweb.
