Warn user about specifying reviewers that are away

Summary:
There are different options how to implement this:
We can also generate the warning in `validateField()` and handle it in all callsites.
This is sufficient for me and simple enough.

Test Plan: `arc diff` revision with reviewer away/not away.

Dispatch a "diff.willBuildMessage" event from Arcanist

Summary:
Hive has custom integration which relies on prefilling a bunch of information from JIRA. This is currently broken and accomplished in a roundabout way. Instead, add an event that the integration can listen for. See next diff.

@Girish, I guess you're official Phabricator/Hive support now?

Test Plan: Ran the Hive/JIRA workflows in Git and SVN, see next diff.

Bump Conduit client version

Summary:
Several related changes:

  - Add a "--conduit-version" flag, so you can actually diff conduit version bumps. Otherwise, the server rejects you.
  - Make "arc upgrade" upgrade both libphutil and arcanist, not just arcanist.
  - Bump the version number to 5. See D2527.

Test Plan:
  - Ran "arc upgrade".
  - Ran "arc diff". Got told there was a version issue.
  - Ran "arc diff --conduit-version=4" to create this diff.

PHPUnit test engine

Summary:
PHPUnit wrapper for arc.
The idea here is simple - find the test case which is related to the updated
class file. Generate tmp files for json & clover reports, run phpunit
with provided arguments.
It supports phpunit configuration file setting in `.arcconfig`: `phpunit_config`.
Path should be relative to project root.

Test Plan:
- Set `unit_engine` to `PhpunitTestEngine`
- Try running tests with & without `phpunit_config` option.

PHPUnit test name handling improvements

Summary:
Better test name handling for tests with data sets.
Instead of showing test name with full data set, show it's id/name,
e.g. `testConstructor with data set #1`

Improve default fill of Differential messages from commits

Summary:
  - When you run "arc diff" in Mercurial, we currently give you an empty template. Instead, prefill a likely template by parsing messages, as we do for Git.
  - Unify Git and Mercurial logic for acquiring messages, since `getLocalCommitInformation()` now provides this information. This should improve Git performance, and allows us to delete some code.
  - Merge messages more intelligently. Currently, we just overwrite fields. Instead, merge arrays (like ccs, reviewers, tasks) and concatenate strings (like summary and test plan). We need to special case "title", see inline.
  - @csilvers: this is a precursor to implementing "--reviewers", etc.

Test Plan: See next post, test plan includes giant output.

Remind user about 'arc amend' when they try to land a branch onto itself

Summary: If you develop in "master" and try to "arc land", you get an error. You can reasonably "arc amend" in this situation, most of the time. Give the user an explicit pointer.

Test Plan:
  $ arc land master
  Usage Exception: You can not land a branch onto itself -- you are trying to
  land 'master' onto 'master'. For more information on how to push changes, see
  'Pushing and Closing Revisions' in 'Arcanist User Guide: arc diff' in the
  documentation. You may be able to 'arc amend' instead.

Fix arc ArcanistSvnHookPreCommitWorkflow

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.

Test Plan:
changed --transaction to --revision in related code and manually ran the following command. It detected the syntaxt error correctly. 558937 is a revision with syntax error.

/usr/local/bin/php -f /home/jungejason/nfs_devtools/arcanist/bin/arc svn-hook-pre-commit     --load-phutil-library=/tmp/testwww/www/lib/arcanist --load-phutil-library=/home/jungejason/nfs_devtools/facebook/src /svnroot 558937 2>&1
