Durham Goode 2f853a6c50 treemanifest: improve integration with fastmanifest 
Summary:
Previously treemanifest and fastmanifest were largely unaware of each other. If
the fastmanifest was available, we'd use that. If not, we'd try tree. Then we'd
fall back to flat. When comparing two manifests, this could cause problems since
if one manifest was fast and one was tree, we'd have to fall all the way back to
flat manifests to compare them.

This patch adds the ability to build a treemanifest from a fastmanifest for
inmemory manifests that were copied from a commit that has both a fastmanifest
and a treemanifest.  We do it by diff'ing the inmemory fastmanifest with the
commit fastmanifest, then applying that diff to the commit's treemanifest. Then
we can compare that tree with the other tree.

This is particularly useful when doing things like 'hg up master' after a pull.
The new master commit probably has a treemanifest, but doesn't yet have a
fastmanifest, while the commit the user is on probably has both. Now we can do
that hg up without having to parse a full manifest.

Once treemanifest has been enabled, every commit (both pulled and user created)
should have treemanifests. Therefore this case should never happen when
comparing two normal commits. So in theory, the only way to hit this case is
when Mercurial does a manifest.copy() on a manifest that has a fastmanifest
(like when reading a workingctx which must copy the commit manifest and apply
working copy changes), since the copy will choose to copy the fastmanifest and
leave the treemanifest behind. This patch addresses that case, so I think there
shouldn't be other cases.

Test Plan: Adds a test that covers this case.

How to run Facebook experimental extensions tests
=================================================

Running the tests
-----------------

To run the tests, `cd` into this directory (./tests/) and run the `run-tests.py`
script from the core Mercurial repository (tests directory too).

For example if you have a 'hg-crew' repository checked out next to this one,
use:

  ../../hg-crew/tests/run-tests.py

Obtaining the test runners
--------------------------

If you do not already have a copy of the Mercurial repository, you can obtains
one with:

  $ hg clone http://mercurial-scm.org/hg

Running against various Mercurial versions
------------------------------------------

By default, the test runners will run against the version of Mercurial in the
repository it lives in. you can run against other version of Mercurial using
the --with-hg=PATH flag. For example to run against the installed version of
Mercurial you can use --with-hg=`which hg`
