cmdutil: changeset_printer: use methods of filectx/changectx.
This allows extensions that modify changeset metadata (e.g.
description) by overriding methods of changectx to get consistent
behavior from all log-like commands, regardless of whether templates
or styles are used. Without this, overriding changectx methods works
if you use styles or templates, but not with default log format.
This meant adding filectx.extra() for consistency with changectx.

use 'echo' to diff repository (or selected files)
Show differences between revisions for the specified files, using the
'echo' program.
When two revision arguments are given, then changes are shown between
those revisions. If only one revision is specified then that revision is
compared to the working directory, and, when no revisions are specified,
the working directory files are compared to its parent.
options:
-o --option pass option to comparison program
-r --rev revision
-c --change change made by revision
-I --include include names matching the given patterns
-X --exclude exclude names matching the given patterns
use "hg -v help falabala" to show global options
