extdiff: correctly handle deleted subrepositories (issue3153)

Previously, when extdiff was called on two changesets where
a subrepository had been removed, an unexpected KeyError would
be raised.

Now, the missing subrepository will be ignored.  This behavior
mirrors the behavior in diffordiffstat from cmdutil.py line
~1138-1153.  The KeyError is caught and the revision is
set to None.

try/catch of LookupError around matchmod.narrowmatcher and
sub.status is removed, as LookupError is not raised anywhere
within those methods or deeper calls.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install:

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help

Running without installing:

 $ make local      # build for inplace usage
 $ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
