Summary:
Fact engines loading dependent objects are super slow because they load them one by one.
This diff put each page in a Lisk set allowing engines to use `loadRelatives()`.
It also introduces `clearSet()` method which is somewhat neccessary in PHP < 5.3 or with disabled cyclic [[ http://php.net/gc | GC ]].
Test Plan:
$iterator = new PhabricatorFactUpdateIterator(new DifferentialRevision());
foreach ($iterator as $revision) {
$diffs = $revision->loadRelatives(new DifferentialDiff(), 'revisionID');
echo memory_get_usage() . "\n";
}
Experienced not-steadily-increasing memory usage and much faster loading.

Summary: PhutilBufferedIterator now implements all the nonspecific logic here.
Test Plan:
Created a test script like this:
$iterator = new LiskMigrationIterator(new DifferentialRevision());
$iterator->setPageSize(3);
foreach ($iterator as $key => $rev) {
echo "{$key}: ".$rev->getID()."\n";
}
Ran it and verified sensible iteration results.

Summary: We pull "retries" and a doc link from PhabricatorEnv directly. Break these dependencies so the classes can move to libphutil.
Test Plan: Browsed site, triggered a schema exception and verified I still got the useful footer text.

Summary: See D3006, D3007. Make it easier to do migrations like that without holding all results in memory.
Test Plan:
Ran this code with an artificially small page size (2):
foreach (new LiskMigrationIterator(new DifferentialRevision()) as $rev) {
echo "Revision ".$rev->getID()."\n";
}
Verified each revision as loaded and processed.

Summary:
Lisk currently behaves in two different ways if you call it like `load("cow")` (throws) versus `load(99999999)` (returns null), where neither ID exists.
This was intended to catch programming errors as distinct from missing data, but in practice the former is very rare and you have to handle the latter in most cases anyway. The case where you pass "0" is particularly confusing. See D2971 for an example.
On the balance, I think this ends up being far more confusing than helpful. Instead, just return NULL if we're sure there's no such object.
Test Plan: Reasoned about program behavior.

Summary:
In unit tests which use fixtures, we open transactions on every connection we establish. However, since we don't track connections that are established with "$force_new" (currently, only GlobalLock connections) we never close these transactions normally.
Instead of not tracking these connections, track them using unique keys so we'll never get a cache hit on them.
Test Plan: Built unit tests on top of this, had them stop dying from unclosed transactions.
