Summary:
I type "arc brnach" about 300 times per day.
- Allow arc commands to be specified by unique prefix ("exp" for "export", "lib" for "liberate").
- Allow arc commands to be specified by unique levenshtein edit distance <= 2 ("brnach" for "branch", "halp" for "help", "ptach" for "patch").
- Reorganize code out of "arcanist.php".
I think this will be uncontentious because arc commands are rarely destructive, but if people complain we can either require certain commands be typed exactly (maybe "land"?) or allow this feature to be disabled in configuration.
Test Plan:
$ arc br
Usage Exception: Unknown command 'br'. Try 'arc help'.

Summary:
Currently, if you run `arc` in arcanist/ or libphutil/ and your PATH and on-disk configuration are set up so a different version of arc or libphutil are the ones that actually load, we fail with an exception like "running arcanist in a different copy of arcanist is not supported".
This causes problems for Harbormaster, since we'd like to be able to run 'arc' in a copy of libphutil/ and have it execute unit tests for that copy rather than failing abruptly. So, if we detect that we're in arcanist/ or libphutil/, execute 'arc' again with the same arguments but force it to load the working copy in place of either the 'arcanist/' or the 'libphutil/' that it decided to load.
This is pretty much horrible black magic.
Test Plan: Ran 'arc list --trace' inside copies of libphutil/ and arcanist/ outside of the normal include chain. Saw it detect these, emit a message, and re-execute itself correctly.

This commit doesn't change license of any file. It just makes the license implicit (inherited from LICENSE file in the root directory).
We are removing the headers for these reasons:
- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.

Currently, when the user types `arc set-config x false`, we set it as the string "false", which is usually not desirable. We have some steps toward typed config already, but expand on what we have and move as much stuff as possible into it, including all the config settings that aren't currently documented (there are still some lint-specific and project-specific settings not present here, but this is most of it).
Also make the `phutil_libraries` key a legacy name for `load`, and `immutable_history` a legacy name for `history.immutable`. Generally the goal here is to make config simpler and bring it more in-line with Git/Mercurial, which use dotted hierarchies.
I'll add some documentation here but I think most of the changes should be fairly straightforward.
Test Plan:
- `arc set-config history.immutable on` (And similar -- sets to boolean true.)

Summary:
- Add flags to exit after an idle time or client count.
- Add flags to control daemonization.
- Add flags to control output.
- Add flags to skip the "hello" frame of the protocol.
- Make the client launch a server if one does not exist.
The one-time overhead to launch a server and run a command through it looks to be ~130% of the overhead to run the command directly with "hg", so even if we never run a second command we're not paying too much.
The incremental overhead to run subsequent command appears to be less than 3% of the overhead to run the command directly with "hg" (and maybe less than 1%, I'm not sure how long the computation part of a command like 'hg log' "actually" takes).
The overhead to launch a PHP client, connect to an existing server, run a command, and then print it and exit is roughly 50% of the overhead to run the command directly with "hg". So theoretically a user can achieve an amortized 2x performance increase for all 'hg' commands by aliasing 'hg' to the PHP client in their shell.
Test Plan:
- Ran servers with idle and client count limits, let them idle and/or hit their connection limits, saw them exit.
- Ran foreground and background servers.
- Ran a daemon server with redirected stdout/stderr. Verified logs appeared.
- Ran with --quiet.
- Ran clients and servers with and without --skip-hello, things work if they agree and break if they disagree. The throughput gain on this is fairly small (maybe 5%?) but it seems simple enough to keep for the moment.
- Ran serverless clients and verified that servers launched the first time, were available subsequently, and relaunched after 15 seconds idle.

Instead, ship with a list of functions which are provided by extensions that we'll ignore when calculating dependencies, so not having pcntl doesn't mean you have to excuse through irrelevant errrors every time.

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.

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.
