streamclone: also stream caches to the client
When stream clone is used over bundle2, relevant cache files are also streamed.
This is expected to be a massive performance win for clone since no important
cache will have to be recomputed.
Some performance numbers:
(All times are wall-clock times in seconds, 2 attempts per case.)

(since ssh and lan are not affected, there seems to be an issue with how we
read/write the http stream on connection with latency, unrelated to the format)

caches: make 'cachetocopy' available in scmutil
For more code to use this information, we need it to be more publicly available.

streamclone: add support for cloning non append-only file
The phaseroots are stored in a non append-only file in the repository. We
include them in the stream too. Since they are not append-only, we have to
keep a copy around while we hold the lock to be able to stream them later.
Since phase get exchanged within the stream we can skip requesting them
independently.
As a side effect, this will fixes issue5648 once the feature is enabled by
default.

streamclone: tests phase exchange during stream clone
We add a test dedicated to phases. As reported in issue 5648 stream from a non publishing
server is currently broken (does not preserve the phase). We'll fix it with 'v2'
support in the next changesets.
Boris Feld <boris.feld@octobus.net> [Wed, 17 Jan 2018 16:41:44 +0100] rev 35763
streamclone: add support for bundle2 based stream clone
The feature put to use the various bits introduced previously. If the server
supports it, the client will request its stream clone through bundle2 instead of
the legacy 'stream_out' commands. The bundle2 version use the better 'v2'
version of stream bundles.
The 'v2' format is not finalized yet. Now that there are some code running it,
we can start working on it again.
Performance numbers are available at the end of this series.
