dirstate: subclass the new dirstate Protocol class

Behold the chaos that ensues.  We'll use the generated *.pyi files to apply type
annotations to the interface, and see how much agrees with the documentation.

Since the CamelCase name was used to try to work around pytype issues with zope
interfaces and is a new innovation this cycle (see c1d7ac70980b), drop the
CamelCase name.  I think the Protocol classes *should* be CamelCase, but that
can be done later in one pass.  For now, the CamelCase alias is extra noise in
the *.pyi files.

#require no-windows no-rhg

XXX-RHG this test hangs if `hg` is really `rhg`. This was hidden by the use of
`alias hg=rhg` by run-tests.py. With such alias removed, this test is revealed
buggy. This need to be resolved sooner than later.

Kludge to emulate timeout(1) which is not generally available.
