Summary:
Ref T2683. At least locally, browse views are now nearly instantaneous, even in Mercurial. We also fall back to what we were doing before if we miss or take too long, so this shouldn't make things very much worse even in extreme cases.
For a local `hg` repo, the time we spend pulling browse stuff has dropped from ~3,000ms to ~20ms. This is probably atypical, but not completely crazy or rigged or anything.
Test Plan: Viewed Git, Subversion and Mercurial repositories and observed dramatically better performance in Git and Mercurial as they took advantage of the cache.

Via HackerOne. In regular expressions, "$" matches "end of input, or before terminating newline". This means that the expression `/^A$/` matches two strings: `"A"`, and `"A\n"`.
When we care about this, use `\z` instead, which matches "end of input" only.
This allowed registration of `"username\n"` and similar.

Ref T4276. When a change is larger than 2GB, PHP can not read the entire change into a string, so Herald can not process it.
Additionally, we already have a time limit for practical reasons, but it's huge (probably incorrectly). To deal with these things:
- Add an optional byte limit to `diffusion.rawdiffquery`.
- Make the query with a 1GB limit.
- Reduce the diff timeout from 15 hours to 15 minutes.
- Add a "Changeset is enormous" field. This field is true for changes which are too large to process.
This generally makes behaviors more sane:
- We'll always make progress in Herald in a reasonable amount of time.
- Installs can write global rules to handle (or reject) these types of changes.

Summary:
Ref T1493. Diffusion has some garbagey behavior for things we can't resolve. Common cases are:
- Looking at a branch that doesn't exist.
- Looking at a repository with no branches.
- Looking at a commit that doesn't exist.
- Looking at an empty repository.
In these cases, we generally fatal unhelpfully. I want to untangle this mess.
This doesn't help much, but does clean things up a bit. We currently have two separate query paths, "stablecommitname" and "expandshortcommit". These are pretty much doing the same thing -- taking some ref like "master" or "default" or a tag name or part of a commit name, and turning it into a full commit name. Merge them into a single "resolverefs" method.
This simplifies the code a fair bit, and gives us better error messages. They still aren't great, but they're like this now:
Ref "7498aec194ecf2d333e0e2baddd9d5cdf922d7f1" is ambiguous or does not exist.
...instead of just:
ERR-INVALID-COMMIT
