Summary:
Fixes T5492. I figured this would be easier to just fix than write a guide for; it actually took me an hour, but I spent like 75% of that futzing with my editor.
- The Move controller currently accepts either a slug or an ID. I can't find any callsites which pass a slug, and this doesn't make sense. Pretty sure this was copy/pasted from Edit or something. Only accept IDs.
- Slightly modernize the Move controller (newDialog(), handleRequest(), $viewer).
- When the user enters a bad slug, warn them that we're going to fix it for them and let them accept or reject the changes.
- Don't prefill the edit note (this feels inconsistent/unusual).
- On the form, label the input "Path" instead of "URI".
- Show the old path, to help remind the user what the input should look like.
- When a user tries to do a no-op move, show a more tailored message.
- When the user tries to do an overwriting move, explain how they can fix it.
- When normalizing a slug like `/question/???/mark/`, make it normalize to `/question/_/mark`.
Test Plan:
- Tried to move a document to itself.
- Tried to overwrite a document.
- Did a bad-path move, accepted corrected path.
- Did a good-path move.
- Did a path move with a weird component like `/???/`.
- Added and executed unit tests.

Summary:
Fixes T5934. If you hash a password with, e.g., bcrypt, and then lose the bcrypt hasher for some reason, we currently fatal when trying to figure out if we can upgrade.
Instead, detect that the current hasher implementation has vanished and let the user reset their password (for account passwords) or choose a new one (for VCS passwords)>
Test Plan:
Account password:
- Artifically disabled bcrypt hasher.
- Viewed password panel, saw warnings about missing hasher.
- Used password reset workflow to change password, saw iterated MD5 hashed password get set.
- Enabled bcrypt hasher again.
- Saw upgrade warning.
- Upgraded password to bcrypt.
VCS password:
- Artificially disabled bcrypt hasher.
- Viewed password panel, saw warnings about missing hasher.
- Reset password.
- Saw iterated md5 password.
- Reenabled bcrypt.
- Upgraded to bcrypt.

instead of CRYPT_BLOWFISH. Using CRYPT_BLOWFISH is not supported in either PHP

No matter what password entered, it will always fail authentication. After this

There are quite a few tests in Arcanist, libphutil and Phabricator that do something similar to `$this->assertEqual(false, ...)` or `$this->assertEqual(true, ...)`.
This is unnecessarily verbose and it would be cleaner if we had `assertFalse` and `assertTrue` methods.

Summary:
Ref T4443. In addition to performing upgrades from, e.g., md5 -> bcrypt, also allow sidegrades from, e.g., bcrypt(cost=11) to bcrypt(cost=12). This allows us to, for example, bump the cost function every 18 months and stay on par with Moore's law, on average.
I'm also allowing "upgrades" which technically reduce cost, but this seems like the right thing to do (i.e., generally migrate password storage so it's all uniform, on average).
Test Plan:
- Fiddled the bcrypt cost function and saw appropriate upgrade UI, and upgraded passwords upon password change.
- Passwords still worked.
- Around cost=13 or 14 things start getting noticibly slow, so bcrypt does actually work. Such wow.

Summary:
Ref T2632. Fixes T1466.
Currently, we normalize slugs (and thus Phriction URIs and canonical project names) to a small number of latin characters. Instead, blacklist a few characters and permit everything else (including utf8 characters).
When generating Phriction URIs, encode any utf8 characters. This means we render URIs encoded, but browsers handle this fine and display them readably in the URI and address bar, etc.
The blacklisted characters are mostly for practical reasons: \x00-\x19 are control characters, `#%?` are meaningful in URIs, `+` is sometimes configured to be interprted as space by apache, etc., `<>\\` are just silly, `&= ` are largely cosmetic.
This allows some silly stuff, like generating URIs with zero-width spaces and RTL markers in them. Possibly we should go blacklist those characters at some point.

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.

Summary:
We currently cache all connections in LiskDAO so we can roll back transactions when fixtured unit tests complete.
Since we establish a new connection wrapper each time we establish a global lock, this cache currently grows without bound.
Instead, pool global lock connections so we never have more than the largest number of locks we've held open at once (in PullLocalDaemon, always 1).
Another way to solve this is probably to add an "onclose" callback to `AphrontDatabaseConnection` so that it can notify any caches that it been closed. However, we currently allow a connection to be later reopened (which seeems reasonable) so we'd need a callback for that too. This is much simpler, and this use case is unusual, so I'd like to wait for more use cases before pursing a more complicated fix.
Test Plan:
Ran this in a loop:
while (true) {
for ($ii = 0; $ii < 100; $ii++) {
$lock = PhabricatorGlobalLock::newLock('derp');
$lock->lock();
$lock->unlock();
}
$this->sleep(1);
}
Previously it leaked ~100KB/sec, now has stable memory usage.

Summary:
- For context, see T547. This is the last (maybe?) in a series of diffs that
moves us off raw sha1() calls in order to make it easier to audit the codebase
for correct use of hash functions.
- This breaks CSRF tokens. Any open forms will generate an error when
submitted, so maybe upgrade off-peak.
- We now generate HMAC mail keys but accept MAC or HMAC. In a few months, we
can remove the MAC version.
- The only remaining callsite is Conduit. We can't use HMAC since Arcanist
would need to know the key. {T550} provides a better solution to this, anyway.

- Verified CSRF tokens generate properly.
- Manually changed CSRF to an incorrect value and got an error.
- Verified mail generates with a new mail hash.
- Verified Phabricator accepts both old and new mail hashes.
- Verified Phabricator rejects bad mail hashes.
