fix bad assumption about uniqueness of file versions
Mercurial had assumed that a given file hash could show up in only one
changeset, and thus that the mapping from file revision to changeset
was 1-to-1. But if two people perform the same edit with the same
parents, we can get an identical hash in different changesets.
So we've got to loosen up our uniqueness checks in addgroup and in
verify.

merge: short-circuit search for merge into empty repo
We should have 3 cases for merge:
- - we have no changesets
- - we have less than half the changesets
- - we have more than half the changesets
For no changesets, we can immediately tell that we need everything.
This happens when we initially branch from a remote repo, so we simply shortcircuit the search and grab everything from the root
When we're actually tracking a project, we should generally have most
of the changesets, so the current search algorithm should minimize
searching.
It should rarely occur that upstreams gets far ahead of us, in which
case, we suffer a longer search.

It was copied from the HG: comment lines that are added to the commit.
Then I wrote this commit message, signed it, then closed the commit.
The manifest hash is a hash of all the files in the project together
with the hashes of manifest's parents. Thus, signing the manifest hash
allows us to verify the entire state of project at the time of the

This is more intelligent/efficient by combining neighboring inserts,
replaces and deletes. Passes test of converting kernel repo, but
doesn't appear to substantially affect compression or performance.
This ought to use package_data but that doesn't exist in Python 2.3.
So we do a hack of install_data and use glob.
This also adds templatepath() to hgweb.py which finds the templates
relative to hgweb.py's location.
The old ancestor algorithm could get fooled into returning ancestors
closer to root than it ought to. Hopefully this one, which strictly
orders its search by distance from room, will be foolproof.
If you merge with a repo that has deleted a file after editing it, hg
attempted to resolve the file. This (correctly) resulted in hg verify
errors because the resolved version didn't show up in the manifests.
This moves the manifest resolution before file resolution and decides
which files to resolve based on the (partially) resolved manifest.
After files are resolved, the final manifest is committed.

mercurial 0.4d had the same problems with removing files, but
attached is a patch which fixes that problem.
The key change is in dircache.remove():
del self[f] should have been del self.map[f]
This error was hidden by the 'except: pass' statement.
