Summary:
This need a bunch of work, but is a sort of minimum viable product for the hgdaemon.
The two ProtocolChannels implement the client and server halves of the protocol.
The Server implements the server logic, the Client implements the client logic.
Test Plan: Launched a server and client on the same repo, got hg output in ~2-3ms instead of 100ms+.

We run all tests before deploy but some of them are expected to fail.
We need to skip them.
It can be useful also for someone else.
I don't propagate this to `arc diff` as that would be much more complicated - we would need a new state 'partially skipped'.
The 'path' argument needs to be a file, skipping whole dirs is not supported.
The 'path' argument is in fact engine specific and engines can support format like 'Class::testMethod' but I didn't bother to document it to not confuse people.

`arc unit --skip test.php`
`arc unit --skip ../src/test.php`

Summary:
This adds basic support for mutable history for arc diff and arc amend for
mercurial. This is purely opt-in (so it shouldn't affect anyone who doesn't want
this feature) by explicitly setting
"immutable_history" : false
in arc configuration.
This also fixes another instance of weird behaviour for multiple heads - the
first instance was fixed here:
https://github.com/facebook/arcanist/pull/28
Test Plan:
without "immutable_history" turned on)>
When ##arc diff## produces an update diff, it should list only commits that are
ancestors of the current revision - not ones from other heads.

Summary:
Currently, when a file has a syntax error and you run "arc liberate", the symbol analyzer will fail and throw, which will make the mapper fail and throw, which will make arc fail and throw. This gives you a stack trace pile three scripts deep which is a giant pain to analyze visually.
Instead, raise a clear message.

Summary:
Khan Academy is looking into lint configuration, but doesn't use ".arcconfig" because they have a large number of repositories. Making configuration more flexible generally gives us more options for onboarding installs.
- Currently, only project config (".arcconfig") can load libraries. Allow user config ("~/.arcrc") to load libraries as well.
- Currently, only project config can set lint/unit engines. Allow user config to set default lint/unit engines.
- Add some type checking to "arc set-config".
- Add "arc set-config --show".
Test Plan:
- **load**
- Ran `arc set-config load xxx`, got error about format.
- Ran `arc set-config load ["apple"]`, got warning on running 'arc' commands (no such library) but was able to run 'arc set-config' again to clear it.
- Ran `arc set-config load ["/path/to/a/lib/src/"]`, worked.
- Ran `arc list --trace`, verified my library loaded in addition to `.arcconfig` libraries.
- Ran `arc list --load-phutil-library=xxx --trace`, verified only that library loaded.
- Ran `arc list --trace --load-phutil-library=apple --trace`, got hard error about bad library.
- Set `.arcconfig` to point at a bad library, verified hard error.
- **lint.engine** / **unit.engine**
- Removed lint engine from `.arcconfig`, ran "arc lint", got a run with specified engine.
- Removed unit engine from `.arcconfig`, ran "arc unit", got a run with specified engine.
- **--show**
- Ran `arc set-config --show`.
- **misc**

Summary:
For `PhutilSymbolLoader` queries which include `setAncestorClass()`, we need the map of which classes/interfaces things extend/implement to issue the query efficiently.
Without this map, we need to load //every// class/interface and then do `is_subclass_of()`. This is doable, but not very performant if we don't have php-fpm warmup. There are a few performance-sensitive interfaces where we run queries like this, including some in Arcanist, where we'll never have warmup.
This map isn't particularly difficult to generate or maintain, so just include it in symbol generation and in the library map.
Also set parallelism with a flag, since it was arbitrarily hard-coded and adding flags is easy. 8 actually seems approximately optimal on my machine at least, though.
Test Plan: Ran "phutil_rebuild_map.php", opened library map, got a reasonable extension map.

Summary:
Modernize `phutil_mapper.php` to prepare for killing `__init__.php`.
The current mapper is module-oriented and complex. Instead, make the mapper file-oriented and simpler.
We build a one-to-one cache of file content to symbols (built with `phutil_symbols.php`) and then write a simpler map. See some discussion in D2561.
Also make the script less messy/bad in general. It may be useful to compare this to phutil_mapper.php.
(Additionally, we now write versions into the library map and cache.)
NOTE: Nothing can read this new map right now, of course.
Test Plan: Ran "phutil_rebuild_map.php src/" in phabricator/ with --quiet, --drop-caches, etc. Verified cache file, cache behavior, and generated map output.

With the current order of the include_path (checking in the parent dir of
arcanist last), it is possible to load the wrong libphutil which can have
bad side effects. Instead, the first place we check in include_path should
be the parent dir of arcanist.
(The issue I ran into is that I had a checkout of libphutil in my homedir,
and I was running arc from my homedir with --load-phutil-library to load
the libraries, and since ./ is the default value for include_path, we were
loading libphutil from my homedir instead of from alongside the copy of arc
that I was running. The libphutil alongside that copy of arc worked, but my
checkout of libphutil had D2545 in it, so it was broken.)

Summary:
there are two problems making the ArcanistSvnHookPreCommitWorkflow not working.
- pathExists($path) will always return false because it hasn't loaded the path yet. Because of this, PhutilLintEngine will unset the path at https://secure.phabricator.com/diffusion/ARC/browse/master/src/lint/engine/phutil/PhutilLintEngine.php;032b9b30b0721c3f$46, so ArcanistSvnHookPreCommitWorkflow will have no path to lint against and never detects a problem.
- In ArcanistSubversionHookAPI::getCurrentFileData(), the $path is already the full path in svnroot (path got from https://secure.phabricator.com/diffusion/ARC/browse/master/src/workflow/svn-hook-pre-commit/ArcanistSvnHookPreCommitWorkflow.php;032b9b30b0721c3f$72). Prepending the project root to it will make the file path to be wrong so that the file content is empty. Again, ArcanistSvnHookPreCommitWorkflow never detects a problem.
