Summary:
Usually LFS files are binary files. But there could be exceptions. This diff
adds a new customized field `x-is-binary` to record those exceptions.
The `filectx.isbinary` API is changed to use that metadata as a fast path.
This allows us to provide a transparent user experience (whether a file is
stored in LFS or not does not affect its original `isbinary` property),
while still being able to skip loading the LFS blob if the file is binary.
Test Plan: Added a new test case

Summary:
D4865150 and D4934720 aren't effective in our current setup. The direct
cause in the code is because the server couldn't find common marker version:
```
# old server-side code, returns empty in our current setup
obsolete.commonversion(bundle2.obsmarkersversion(reply.capabilities))
```
Upon investigation, it's because there is no `exchange` enabled client-side.
But we do want one-way (server->client) markers for the rebased commits, as
long as obsstore is enabled (createmarkers is set, without exchange).
The upstream expects the server to have obsstore enabled, and exchange
enabled, to send markers. Since we are generating markers without an
obsstore (see D4865150), we are on our own way. This diff makes it one step
further.
This diff adds an explicit parameter to the `b2x:rebase` part to tell the
server what obsmarker format the client supports so the server could make a
right decision without relying on the "standard" `reply.capabilities`, which
is affected by the exchange option.
Test Plan: Change the existing test, make sure the old code fails.

Summary:
An `hg pull` test triggers the following code path server-side when using
remotefilelog:
...
remote: File "/usr/lib64/python2.7/site-packages/remotefilelog/remotefilelogserver.py", line 308, in streamer
remote: text = _loadfileblob(repo, cachepath, path, node)
remote: File "/usr/lib64/python2.7/site-packages/remotefilelog/remotefilelogserver.py", line 223, in _loadfileblob
remote: text = createfileblob(filectx)
remote: File "/usr/lib64/python2.7/site-packages/remotefilelog/remotefilelogserver.py", line 348, in createfileblob
remote: ancestors.extend([f for f in filectx.ancestors()])
remote: File "/usr/lib64/python2.7/site-packages/mercurial/context.py", line 1072, in ancestors
remote: for parent in c.parents()[:cut]:
remote: File "/usr/lib64/python2.7/site-packages/mercurial/context.py", line 923, in parents
remote: r = fl.renamed(self._filenode)
remote: File "/usr/lib64/python2.7/site-packages/mercurial/filelog.py", line 62, in renamed
remote: t = self.revision(node)
...
That triggers downloading a blob. We don't want to do that server-side. So
override the `renamed` method to use LFS fast path to test rename.
Practically, this reverts part of D4906074.
Test Plan: Run existing tests. This change was made on the server.

The main rationale for this change is that I've got years of use
patterns on bisect where I *start* bisect by running 'hg bisect
--reset', not *finish* with that command, so `hg status` with
morestatus enabled is spewing annoyances in nearly every repository
I've ever used. It wasn't any harder to allow people to ignore
anything they want, but (at least for now) bisect is the only state
that seems "special" in that it doesn't have a definite "end" that
Mercurial can detect and automatically clean up. I'd also be fine with
adding something like morestatus.ignorebisect if we want to avoid a
potential footgun where a user could ignore rebase state.
Summary:
It should've probably been using this function from the beginning, I just
forgot. Let's switch it to use _findnode so it takes advantage of the new
indexes.
This changes the return value of _findnode, but that's fine because the only
caller was getmissing() which didn't use the return value.
Test Plan: Ran the tests. The getnodeinfo unit test covers this code path.

Summary:
Previously looking up a particular node in a histpack required a bisect to find
the file section, then a linear scan to find the particular node. If you needed
to look up the latest 3000 nodes one by one, that involved 3000 linear scans,
many of which traversed the same nodes over and over.
This patch adds additional index at the end of the current histidx file. In a
future patch, we will change getnodeinfo() to use this index instead of the
linear scan logic.
Test Plan:
Ran the tests. I haven't actually verified that the data in these
indexes is correct. My next patch will add logic that reads these indexes and
will add tests around it. I won't land this until I've confirmed it's correct.

Test Plan:
Ran the tests. I also ran the tests with some debug code to manually
force the sha to include 0 instead of 1 and verified that the hash didn't change
(which confirms that all of these hash changes are just because of that one byte
version change).

Summary:
`bundlefile` variable wasn't initialized if `head in nodestobundle` were true.
Even worse, the previous version of `bundlefile` were used. That means that in
some cases infinitepush sends back a wrong bundle.
Adding a unittest is quite tricky because problem shows up only in one rare
case. Example: we have a stack of 2 commits A and B and each commit in the
stack has a bookmark that points to it. Then `getbundlechunks()` `heads`
parameter contains two heads: commit A and commit B in undefined order.
If it happens that first element in the list is commit A we'll create a bundle
that contains only commit A. And we'll reuse the same bundle when we process
commit B. That means that we'll send the same bundle with commit A twice,
but no bundles with commit B.
I refactored the code to make sure we won't get the same bug in
the future.

We are generating multiple manifests in memory. When we are trying to
read the previous manifest and doing a changelog lookup, we might trigger a bug
in Mercurial. Mercurial tries to use the 00changelog.d file instead of the .i file once it
reached a certain size. As this is all happening in one big transaction,
Mercruial is supposed to read this from in-memory, but this is broken atm. We
can circumvent this bug by reusing the manifestnode that we generated in the
previous iteration. This is more effective anyway.

Summary:
We've modified arcanist a while ago so that if it doesn't find user/cert information for the specific URL that it's using, it just picks the user/cert information from any other URL in ~/.arcrc. This is because it's essentially always the same user, and always the same cert, so there's really no point in being too picky.
This updates hg extension to be almost as careless. It will attempt to find the matching user/cert, but if it doesn't work, it'll just pick any cert if available.
Test Plan:
Without this change, "hg ssl" in a recent version of www reports an warning because www/.arcconfig has phabricator.intern.facebook.com, where default ~/.arcrc's have phabricator.fb.com.
With this change, "hg ssl" succeeds to display revision information because it is once again able to authenticate with conduit

Summary:
We have to use the dummy store to ensure we don't try to open an HTTP
connection during push, which can fail and must not happen during p4fastimport.
However `dummy` requires some configuration. So just add an internal `null`
store that allows us to operate LFS in a mode that will ignore all large files
completely.
Test Plan: used it in p4fastimport

Summary:
To enable pushing between peers (and eventually pushing to the server), let's
teach bundle creation to include the trees being pushed.
Test Plan: Adds a test

Summary:
Previously the server would access the tree data in an adhoc manner. Sometimes
it would talk straight to revlogs, sometimes it would create stores and talk to
data packs. This patch makes it access trees the same way clients do, through
repo.svfs.manifestdatastore and manifesthistorystore.
This also cleans up the client store creation just a little and adds a
unionmetadatastore for unified history access.
Test Plan: Ran the tests
