Ref T8424. This adds a standard KeyValueCache to serve as a request cache.
In particular, I need to cache Spaces (they are frequently accessed, sometimes by multiple viewers) but not have them survive longer than the scope of one request.
This request cache is explicitly destroyed by each web request and each daemon request.
In the very long term, building this kind of construct supports reusing PHP interpreters to run web requests (see some discussion in T2312).
Test Plan:
- Added and executed unit tests.
- Ran every daemon.

Summary:
Fixes T6692. Addresses two main issues:
- The write guard would sometimes not get disposed of on exception pathways, generating an unnecessary secondary error which was just a symptom of the original root error.
- This was generally confusing and reduced the quality of reports we received because users would report the symptomatic error sometimes instead of the real error.
- Instead, reflow the handling so that we always dispose of the write guard if we create one.
- If we missed the Controller-level error page generation (normally, a nice page with full CSS, etc), we'd jump straight to Startup-level error page generation (very basic plain text).
- A large class of errors occur too early or too late to be handled by Controller-level pages, but many of these errors are not fundamental, and the plain text page is excessively severe.
- Provide a mid-level simple HTML error page for errors which can't get full CSS, but also aren't so fundamental that we have no recourse but plain text.
Test Plan:
Mid-level errors now produce an intentional-looking error page:
{F259885}
Verified that setup errors still render properly.
@chad, feel free to tweak the exception page -- I just did a rough pass on it. Like the setup error stuff, it doesn't have Celerity, so we can't use `{$colors}` and no other CSS will be loaded.

Summary:
Ref T5702. This is a forward-looking change which provides some very broad API improvements but does not implement them. In particular:
- Controllers no longer require `$request` to construct. This is mostly for T5702, directly, but simplifies things in general. Instead, we call `setRequest()` before using a controller. Only a small number of sites activate controllers, so this is less code overall, and more consistent with most constructors not having any parameters or effects.
- `$request` now offers `getURIData($key, ...)`. This is an alternate way of accessing `$data` which is currently only available on `willProcessRequest(array $data)`. Almost all controllers which implement this method do so in order to read one or two things out of the URI data. Instead, let them just read this data directly when processing the request.
- Introduce `handleRequest(AphrontRequest $request)` and deprecate (very softly) `processRequest()`. The majority of `processRequest()` calls begin `$request = $this->getRequest()`, which is avoided with the more practical signature.
- Provide `getViewer()` on `$request`, and a convenience `getViewer()` on `$controller`. This fixes `$viewer = $request->getUser();` into `$viewer = $request->getViewer();`, and converts the `$request + $viewer` two-liner into a single `$this->getViewer()`.
Test Plan:
- Browsed around in general.
- Hit special controllers (redirect, 404).
- Hit AuditList controller (uses new style).

Summary:
Fixes T6044. We've had two cases (both the same install, coincidentally) where pages got hung doing too much data fetching.
When pages hang, we don't get a useful stack trace out of them, since nginx, php-fpm, or PHP eventually terminates things in a non-useful way without any diagnostic information.
The second time (the recent Macros issue) I was able to walk the install through removing limits on nginx, php-fpm, php, and eventually getting a profile by letting the page run for several minutes until the request completed. However, this install is exceptionally technically proficient and this was still a big pain for everyone, and this approach would not have worked if the page actually looped rather than just taking a long time.
Provide `debug.time-limit`, which should give us a better tool for reacting to this situation: by setting it to a small value (like 10), we'll kill the page after 10 seconds with a trace, before nginx/php-fpm/php/etc can kill it uselessly. Hopefully that will be enough information to find the issue (generally, getting a trace has been 95% of the problem in the two cases we've encountered).
Test Plan: Set this option to `3` and added a sleep loop, saw a termination after 3 seconds with a useful trace.

Every time a user makes a request, give their IP address some points. If they get too many points in 5 minutes, start blocking their requests automatically for a while.
We give fewer points for logged in requests. We could futher refine this (more points for a 404, more points for a really slow page, etc.) but let's start simply.
Also, provide a mechanism for configuring this, and configuring the LB environment stuff at the same time (this comes up rarely, but we don't have a good answer right now).

We currently hard-require this in setup. We do not need to; we don't actually need it until we start running daemons. Move it to post-install and provide more guidance.
We could make this even easier in the future, but we'd need to special case it, since it's dangerous to let it be set to any value (if you set it to the wrong value, you can't log in). We could safely have a workflow which writes the current request URI into the database configuration, or a two-stage workflow where we set the URI and then verify it, but these both imply some special casing and complication. This should be a step forward from where we are today, regardless.

This is basicaly a light version of D4286. The major problem with D4286 is that it's a huge leap and completely replaces the setup process in one step.
Instead, I want to do this:
- Add the post-setup warnings (yellow bar with "6 unresolved warnings...").
- Copy all setup checks into post-setup warnings (so every check has an old-style check and a new-style check).
- Run that for a little bit and make sure it's stable.
- Implement fatal post-setup checks (the red screen, vs the yellow bar).
- Run that for a little bit.
- Nuke setup mode and delete all the old checks.
This should give us a bunch of very gradual steps toward the brave new world of simpler setup.
Test Plan:
- Faked APC setup failures, saw warnings raise.
- Verified that this runs after restart (get + set).
- Verified that this costs us only one cache hit after first-run (get only).

We try to detect this, but currently only do so effectively for specific file upload forms. Broaden the detection to cover all cases.
