hgweb: teach archive how to download a specific directory or file
The archive web command now takes into account the "file" request entry, if one
is provided.
The provided "file" is processed as a "path" corresponding to a directory or
file that will be downloaded.
With this change hgweb can to process requests such as:
http://mercurial.selenic.com/hg/archive/tip.zip/mercurial/templates
This will download all files on the mercurial/templates directory as a zip file.
It is not possible to specify file patterns ('glob', 'relglob', 'path',
'relpath', 're', 'relre' nor 'set'). The server will reject those with a
403 HTTP error response.
Note that this is a first step to add support for downloading directories from
the web interface. A following patch will modify the archiveentry map entry on
the different templates so that it adds the current folder path to the archive
links.

using rollback or extensions that destroy/modify history (mq,
rebase, etc.) can cause considerable confusion with shared
clones. In particular, if two shared clones are both updated to
the same changeset, and one of them destroys that changeset
with rollback, the other clone will suddenly stop working: all
operations will fail with "abort: working directory has unknown
parent". The only known workaround is to use debugsetparents on
the broken clone to reset it to a changeset that still exists
(e.g. tip).
