util: declare wire protocol support of compression engines

This patch implements a new compression engine API allowing
compression engines to declare support for the wire protocol.

Support is declared by returning a compression format string
identifier that will be added to payloads to signal the compression
type of data that follows and default integer priorities of the
engine.

Accessor methods have been added to the compression engine manager
class to facilitate use.

Note that the "none" and "bz2" engines declare wire protocol support
but aren't enabled by default due to their priorities being 0. It
is essentially free from a coding perspective to support these
compression formats, so we do it in case anyone may derive use from
it.

Forgotten file can be added back (as either clean or modified)

forget and get should have the right order: added but missing dir should be
forgotten before file with same name is added

  $ echo file d > d
  $ hg add d
  $ hg ci -md

  $ echo a > d/a
  $ hg add d/a
