2725586baf Restructure HookEngine to use PushLog records for all operations
Summary:
Ref T4195. This pulls the central logic of HookEngine up one level and makes all the git stuff genrate PushLogs.

In future diffs, everything will generate PushLogs and we can hand those off to Herald.

Test Plan:
Pushed a pile of valid/invalid stuff:

61c934449d Fix fatal in Git hook when a --force push completely rewrites a ref
Summary: Fixes T4224. If you `git merge-base A B`, and they have //no// ancestor, the command exits with an error. Assume errors mean "no ancestry" and continue.

Test Plan: Completely rewrite a repository with a `--force` push.

2ff5541fc5 Record new commits in the push log
Summary:
Ref T4195. Like the previous diffs, these both create a useful log and give us an object to hand off to Herald.

Surface this information in Diffusion, too, and clean things up a little bit.

caa6fdf56d Add a basic push log for recording repository push events
Summary:
Ref T4195. This log serves two purposes:

  - It's a log, so you can see what happened. Particularly, in Git/Hg, there is no other way to tell:
    - Who //pushed// a change (vs committed / authored)?
    - When was a change pushed?
    - What was the old value of some tag/branch before someone destroyed it?
  - We can hand these objects off to Herald to implement pre-commit rules.

This is a very basic implementation, but gets some data written and has a basic UI for it.

Test Plan: {F87339}

d2e9aee16d Reject dangerous changes in Git repositories by default
Summary: Ref T4189. This adds a per-repository "dangerous changes" flag, which defaults to off. This flag must be enabled to do non-appending branch mutation (delete branches / rewrite history).

Test Plan:
With flag on and off, performed various safe and dangerous pushes.

632e1ceda6 Do the heavy lifting for git commit hooks
Summary:
Ref T4189. This doesn't add any rules yet, but does all the heavy lifting to figure out what's changed and put it in a consuamble (if somewhat ad-hoc) datastructure, which lists all the ref and tag modifications and all the new commits in a consistent way.

From here, it should be fairly straightforward to add top-level rules (e.g., ff pushes only).

Test Plan: Output is huge, see comments.

f93c6985ad Support Mercurial pretxnchangegroup hooks
Summary: Ref T4189. Fixes T2066. Mercurial has a //lot// of hooks so I'm not 100% sure this is all we need to install (we may need separate hooks for tags/bookmarks) but it should cover most of what we're after at least.

Test Plan:
  - `bin/repository pull`'d a Mercurial repo and got a hook install.
  - Pushed to a Mercurial repository over SSH and HTTP, with good/bad hooks. Saw hooks fire.

017d6ccd07 Support SVN pre-commit hoooks
Summary:
Ref T4189. This adds SVN support, which was a little more messy than I though. Principally, we can not use `PHABRICATOR_USER` for Subversion, because it strips away the entire environment for "security reasons".

Instead, use `--tunnel-user` plus `svnlook author` to figure out the author.

Also fix "ssh://" clone URIs, which needs to be "svn+ssh://".

Test Plan:
  - Made SVN commits through the hook.
  - Made Git commits, too, to make sure I didn't break anything.

618b5cbbc4 Install pre-commit hooks in Git repositories
Summary:
Ref T4189. T4189 describes most of the intent here:

  - When updating hosted repositories, sync a pre-commit hook into them instead of doing a `git fetch`.
  - The hook calls into Phabricator. The acting Phabricator user is sent via PHABRICATOR_USER in the environment. The active repository is sent via CLI.
  - The hook doesn't do anything useful yet; it just veifies basic parameters, does a little parsing, and exits 0 to allow the commit.

Test Plan:
  - Performed Git pushes and pulls over SSH and HTTP.
