Summary:
Improve performance of large discovery tasks in Git by using subprocess streaming, like we do for Mercurial.
Basically, we save the cost of running many `git log` commands by running one big `git log` command but only parsing as much of it as we need to. This is pretty complicated, but we more or less need it for mercurial (which has ~100ms of 'hg' overhead instead of ~5ms of 'git' overhead) so we're already committed to most of the complexity costs. The git implementation is much simpler than the hg implementation because we don't need to handle all the weird parent rules (git gives us to them easily).
Test Plan:
Before, `discover --repair` on Phabricator took 35s:
real 0m35.324s
user 0m13.364s
sys 0m21.088s
Now 7s:
real 0m7.236s
user 0m2.436s
sys 0m3.444s
Note that most of the time is spent inserting rows after discover, the actual speedup of the git discovery part is much larger (subjectively, it runs in less than a second now, from ~28 seconds before).
Also ran discover/pull on single new commits in normal cases to verify that nothing broke in the common case.

Summary:
The autoclose logic is currently doing a little too much work. We want to parse each commit at most twice:
# When it first appears in the repository.
# When it first appears on an autoclose branch.
These two events might not be distinct (i.e., it might first appear on an autoclose branch).
Currently, to discover commits initially appearing on autoclose branches, we check each branch, determine if it's an autoclose branch or not, and determine if the HEAD is already a known commit on an autoclose branch. This is correct so far, and allows us to ignore branches which either haven't changed or have commits at HEAD which we've already examined.
However, if an autoclose branch has a new commit, we start working backward through it. Prior to this patch, we only stop when we hit commits that we've already discovered lie on this branch. If the branch is new, none of the commits will be discovered on it (they're discovered in general, and likely discovered on other autoclose branches, but not discovered on this branch), so we'll parse all the way back to the root.
Instead, we want to stop when we hit commits that we've already discovered on //any// autoclose branch.
So do that.
Test Plan: Pushed a new branch, then pushed a new commit at HEAD. Ran discovery, verified we rediscovered only 1 commit, not every commit in history.

It seems that Outlook and Mail.app mostly ignores the threading headers and thread primarily by subject.
They are also very picky about the Re: part in the header.
I guess that's because users of these clients often hit Reply when they want to create a new message to the sender of an e-mail.
We need both of these applications to work with the same setting because we don't use multiplexing to prevent sending multiple e-mails to people in lists.
I also believe that the default behavior should just work in most setups.
I've tried several different combinations of putting "Re:" and none of them seems to always work in both clients.
This diff at least adds more abstraction to the code which should prevent copy/paste errors (two fixed by this diff!).

There's also no reason to timeline this anymore since parsing is no longer order-dependent.

See D2418. This merges the commit discovery daemon into the same single daemon, and applies all the same rules to it.
There are relatively few implementation changes, but a few things did change:
- I simplified/improved Mercurial importing, by finding full branch tip hashes with "--debug branches" and using "parents --template {node}" so we don't need to do separate "--debug id" calls.
- Added a new "--not" flag to exclude repositories, since I switched to real arg parsing anyway.
- I removed a web UI notification that you need to restart the daemons, this is no longer true.
- I added a web UI notification that no pull daemon is running on the machine.
NOTE: @makinde, this doesn't change anything from your perspective, but it something breaks this is the likely cause.
This implicitly resolves T792, because discovery no longer runs before pulling.
Test Plan:
- Swapped databases to a fresh install.
- Ran "pulllocal" in debug mode. Verified it correctly does nothing (fixed a minor issue with min() on empty array).
- Added an SVN repository. Verified it cloned and discovered correctly.
- Added a Mercurial repository. Verified it cloned and discovered correctly.
- Added a Git repository. Verified it cloned and discovered correctly.

Summary:
- Add an explicit multiplexing option, and enable it by default. This is necessary for Mail.app to coexist with other clients ("Re:" breaks outlook at the very least, and generally sucks in the common case), and allows users with flexible clients to enable subject variance.
- Add an option for subject line variance. Default to not varying the subject, so mail no longer says [Committed], [Closed], etc. This is so the defaults thread correctly in Gmail (not entirely sure this actually works).
- Add a preference to enable subject line variance.
- Unless all mail is multiplexed, don't enable or respect the "Re" or "vary subject" preferences. These are currently shown and respected in non-multiplex cases, which creates inconsistent results.
NOTE: @jungejason @nh @vrana This changes the default behavior (from non-multiplexing to multiplexing), and might break Facebook's integration. You should be able to keep the same behavior by setting the options appropriately, although if you can get the new defaults working they're probably better.
Test Plan:
Send mail from Maniphest, Differential and Audit. Updated preferences. Enabled/disabled multiplexing. Things seem OK?
NOTE: I haven't actually been able to repro the Gmail threading issue so I'm not totally sure what's going on there, maybe it started respecting "Re:" (or always has), but @cpiro and @20after4 both reported it independently. This fixes a bunch of bugs in any case and gives us more conservative set of defaults.
I'll see if I can buff out the Gmail story a bit but every client is basically a giant black box of mystery. :/
