Summary:
This small change makes a way better user experience. Users usually have one
big repo per host, but they may have many hosts (for example, laptop and
devserver). If we ask for reporoot first then it's very likely that next
`pullbackup` invocation will fail because there will be ambigious hosts.
Let's switch the order.

Summary:
There are a couple of reasons to avoid using ui.username():
1) If config option ui.username is set on the server then it will use it
instead of the name of the user that does push
2) It prints confusing warning `no username found, using '....' instead`
3) In some cases it fails (probably because it calls socket.getfqdn() which
does network request).
Let's use simple util.getuser() function and set username to 'unknown' if
it fails.

This diff allows specifying many patterns, it allows to not specify
patterns at all and also it allows to specify default scratch patterns to fetch
if no patterns were specified. This is useful if there are many auto-generated
bookmarks under the same scratch bookmark pattern.

Summary:
On a big repo with many old heads bundle that is sent to the server can become
big (in some cases even 500 Mb). That looks like a waste of bundlestore space
and will probably make backup and restore slower. Most of the space is taken
by manifest deltas because it prefers to diff manifest against previous commit
in the bundle. There are two possible approaches to reduce the size:
1) Send many small bundles (for example, one bundle per head)
2) Wrap deltaparent function and diff against actual parent previous commit in the bundle.
I chose the second approach for the following reasons:
1) It's easier to implement (main reason)
2) Many bundles probably means slower restore because there will be many requests to the bundlestore instead of just one
With this diff bundle size was reduced from 500 Mb to 8 Mb.
It can potentially increase CPU usage. I'm not sure how bad is it and will investigate it more.

We need to run the tests with:

Summary:
As the name suggest it will restore backup made by `hg pushbackup`.
If user has only one backup for the `dest` repo then it will be restored.
But user may have backed up many local repos that points to `dest` repo.
These local repos may reside on different hosts or in different
repo roots. It makes restore ambiguous; `--reporoot` and `--hostname`
options are used to disambiguate.
Example situation:
1) User has only one laptop with mercurial repo `repo` that was cloned
from remote server. He or she run `hg pushbackup`. Then laptop breaks
and user gets a new one, clones the `repo` again and runs `hg restore`.
It automatically restores the backup.
2) User has devserver and laptop and backups were made from both.
Then if user decides to switch devserver and run `hg restore` on the new
devserver he or she has to specify `--hostname`.
Future plans:
1) Add `--user` option to make it possible to restore another user's backup

Summary:
`bundlerepo` should be closed to ensure that temp file is deleted.
`bundlerepo` creates temp file when bundle is compressed. This is *not* the
case in infinitepush (all our bundle are uncompressed). But seems that
upstream cg1unpacker.compressed() returns True even if bundle is uncompressed.
Also this diff makes `_getoutputbundleraw()` read output bundle in memory
instead of returning a generator. The reason for doing it is because generator
becomes invalid as soon as `bundlerepo` is closed.
This approach will obviously increase memory usage but it shouldn't be a
problem since bundles are small (no more than 10s Mb).

Summary:
infinitepush has been storing bundle1 with changegroups v1. Turned out that in
some cases generated bundles can become huge because v1 changegroups don't
support generaldelta. It makes sense to support all changegroup versions (v1 for BC,
v2 for new infinitepush bundles, and maybe later we'll switch to v3).
To do this we have to store bundle2 instead of bundle1 because bundle1
supports only changegroups v1.

Summary:
We could've avoided creating this diff if bundlerepo supported many bundles.
Unfortunately it doesn't. Adding support requires changes in upstream mercurial and it can take a lot of time.
This implementation wraps `listkeys` to set phases properly and `exchange._changegrouppart` to send more
than one bundle at a time.
It has unsolved problem with phases. For example in this situation
# Publishing server creates commit A (it is marked as draft on the server).
# Client pulls commit A from publishing server (in this case commit A is marked on the client but it's still draft on the server).
# Another client make pull from scratch bookmark. Commit A will be draft on client because we delete publishing = True from listkeys.
We assume that this case is quite rare.

Summary:
Backuping changesets is not enougn for restore. We also want to backup heads
and bookmarks to completely capture the state of the repo.
This diff is the first step in implementing this functionality. It adds new
bundle2 part which contains encoded dict (simple json encoding is used).
If value in the dict is empty then key is the bookmark pattern to delete.
If value is not empty then key is the bookmark name to save and value is a
node hash. The reason to put them in the same part is to make it possible to
delete and insert into indexapi in one transaction. It's also possible to pass
patterns to delete in part parameters but there is a bug in upstream hg that
limits parameters' size to 256 and we can potentially have longer bookmarks.
Local bookmarks are saved in infinitepush in the following form:
infinitepush/backups/USERNAME/HOSTNAME/REPOROOT/bookmarks/LOCAL_BOOKMARK_NAME
Local heads are saved in infintiepush in the following form:
infinitepush/backups/USERNAME/HOSTNAME/REPOROOTheads/HEAD_HASH
Hostname, username and repo root is necessary to distinguish different backups.
