epriestley 7831b92427 Improve LiskDAO::__call() performance
Summary:
This is kind of expensive and can be significant on, e.g., the
Maniphest task list view. Do a little more caching and some clever nonsense to
improve performance.

Test Plan:
Local cost on Maniphest "all tasks" view for this method dropped from
##82,856us## to ##24,607us## on 9,061 calls.

I wrote some unit test / microbenchmark things:

  public function testGetIDCost() {
    $u = new PhabricatorUser();
    $n = 100000;
    while ($n--) {
      $u->getID();
    }
    $this->assertEqual(1, 1);
  }

  public function testGetCost() {
    $u = new PhabricatorUser();
    $n = 100000;
    while ($n--) {
      $u->getUsername();
    }
    $this->assertEqual(1, 1);
  }

  public function testSetCost() {
    $u = new PhabricatorUser();
    $n = 100000;
    while ($n--) {
      $u->setID(1);
    }
    $this->assertEqual(1, 1);
  }

Before:

   PASS  598ms   testSetCost
   PASS  584ms   testGetCost
   PASS  272ms   testGetIDCost

After:

   PASS  170ms   testSetCost
   PASS  207ms   testGetCost
   PASS   29ms   testGetIDCost

Also, ran unit tests.
