Raise a better error for trying to create an empty document in Phriction

Summary:
When you delete the content of a document in Phriction, we treat it as an attempt to delete the document.

In the case you're creating the document, we hit an exception trying to delete a document which doesn't exist yet.

Detect this case and raise a better error.

Test Plan: Tried to create an empty document, got a good error. Created a nonempty document. Edited a document to empty to delete it.

Don't choke on copy-pasted diffs which include commit messages

Summary: If you `git show` and copy/paste it into Differential, we die trying to save the DifferentialChangeset corresponding to the commit message (error: column "filename" can not be null). Instead, drop the message change for raw diffs.

Test Plan: Copy/pasted `git show` into Differential.

Fix static variable usage in Lisk

Summary:
See comment.
This can reveal some pretty bad bugs but HPHP handles this correctly so we already know about them.

Test Plan:
Added `phlog()` to `__call()` and observed what is defined for each method (under PHP). Also:

  class C {
    function __call($name, $args) {
      static $class;
      if (!$class) {
        $class = get_class($this);
      }
      return $class;
    }
  }

  class D extends C {
  }

  class E extends C {
  }

  $d = new D;
  $e = new E;
  var_dump($d->x());
  var_dump($e->x()); // Prints D under PHP!

Use phutil_split_lines() in Differential

Summary:
  - We currently treat "\r" as a newline, but should not because VCSes do not.
  - We get an extra empty line at the end of diffs created after D3442 because we now retain newlines.
  - Historically we've converted tab pre-cache, but do it post-cache instead so we can add prefs about it, as we should handle it better than we do (e.g., let the user set it to a different width, infer width from comments in the file, expand it to actual tab stops, or show it visually in some way).

Test Plan:
  - Verified diffs no longer have an empty line at the end.
  - Created a diff of a "\r" file and verified it displayed somewhat reasonably. All browsers treat "\r" as a real newline so it's not necessarily perfect, but we can clean that up later. Hopefully these files are exceedingly rare.
  - Created a file with tabs and verified it came out reasonably.

Revert "Use phutil_split_lines() in Differential"

This reverts commit f6cb51562efd4f2e599d8ea69c5d5331d4de6d8d.

This has some bugs in normal diffs that I haven't immediately been able to figure out. I'll reapply it once I sort them out.

Restore phutil_split_lines() to Differential

Summary:
Same as D3759 with a fix:

Previously, we would insert `null` to indicate a line that doesn't exist on one side of a diff, and then implode on "\n", so we'd get "\n" as a result.

In D3759, we'd insert `null` but implode on empty string, and get nothing as a result.

When a placeholder null is present, explicitly insert a newline.

Test Plan: D3759 plus examined a diff with removed lines on the left side prior to new lines on the right side.

Defuse a "Host:" header attack

Summary:
Django released a security update recently dealing with malicious "Host" headers:

https://www.djangoproject.com/weblog/2012/oct/17/security/

We're vulnerable to the same attack. Plug the hole.

The risk here is that an attacker does something like this:

  # Register "evil.com".
  # Point it at secure.phabricator.com in DNS.
  # Send a legitimate user a link to "secure.phabricator.com:ignored@evil.com".
  # They login and get cookies. Normally Phabricator refuses to set cookies on domains it does not recognize.
  # The attacker now points "evil.com" at his own servers and reads the auth cookies on the next request.

Test Plan: Unit tests.
