extensions: new closehead module for closing arbitrary heads

``hg close-head`` allows closing arbitrary heads. It is equivalent to
checking out the given revisions and commit an empty change with
``hg commit --close-branch``.

Use a separate usercache, otherwise the server sees what the client commits, and
never requests a transfer.

When the server has some blobs already.  `hg serve` doesn't offer to upload
blobs that it already knows about.  Note that lfs-test-server is simply
toggling the action to 'download'.  The Batch API spec says it should omit the
actions property completely.

Test a corrupt file download, but clear the cache first to force a download.
`hg serve` indicates a corrupt file without transferring it, unlike
lfs-test-server.
