Summary: Ran `arc lint --apply-patches --everything` over rP, mainly to change double quotes to single quotes where appropriate. These changes also validate that the `ArcanistXHPASTLinter::LINT_DOUBLE_QUOTE` rule is working as expected.
Test Plan: Eyeballed it.

Summary: This is still too rough to enable by default. We can turn it on for `secure.phabricator.com` and tweak it a bit first, and then release it in general with higher defaults and more sensible behavior in edge cases.
Test Plan: Loaded some pages.

Summary:
Fixes T3923. On `secure.phabricator.com`, we occasionally get slowed to a crawl when someone runs a security scanner against us, or 5 search bots decide to simultaneously index every line of every file in Diffusion.
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).
Test Plan: Used `ab` and reloading over and over again to hit rate limits. Read documentation.

Summary:
See <https://github.com/facebook/phabricator/issues/487>. If an exception is thrown too high in the stack for the main exception handling to deal with it, we currently never report a stack trace. Instead:
- Always report a stack trace to the error log.
- With developer mode, also report a stack trace to the screen.
Test Plan: Added a high-level `throw` and hit both cases. Got traces in the log and traces-under-developer-mode on screen.

Summary: Ref T3684 for discussion. This could be cleaned up a bit (it would be nice to draw entropy once per request, for instance, and maybe respect CSRF_TOKEN_LENGTH more closely) but should effectively mitigate BREACH.
Test Plan: Submitted forms; submitted forms after mucking with CSRF and observed CSRF error. Verified that source now has "B@..." tokens.

Summary: Ensures that weird behavior from filter_input_array does not remove keys from superglobals. Should fix T3677.
Test Plan:
Checked that $_SERVER contained same number of keys before and after
filtering, and that those affected by the original bug continue to be filtered
correctly.

Summary:
Fixes issue where double-encoding of $_SERVER occurs when php.ini forces all input to be sanitized
Ex:
filter.default = full_special_chars
filter.default_flags = 36
Fix line length
Test Plan: Encountered issue on clean install when registring new user (phusr not defined for email verification). php.ini on that server contains above filter settings. nginx/php-fpm with recommended settings for that server block from setup guide.

Summary:
We have a fair number of conditionals on the existence of the access log. Instead, always build it and just don't write it if the user doesn't want a version on disk.
Also, formalize logged-in user PHID (avoids object existence juggling) in the access log and move microseconds-since-startup to PhabricatorStartup (simplifies index.php).

Summary:
The fixed-position side nav background thing tends to make looking at print_r() output hard. Also, it breaks Ajax, etc.
- Loudly call out unexpected output on normal pages, to catch extra spaces before `<?php`, etc.
- Display unexpected output in an attractive panel on normal pages.
- Log unexpected output instead of breaking Ajax.

Summary:
We have a lot of mess to get through before we can load libphutil and enter Phabricator code properly. Move it to a dedicated class.
I'm probably going to merge PhabricatorRequestOverseer into this, although the check that lives there now is kind of weird. It also does not really need to be a pre-load check and could be handled better.
I stopped shoving stuff in here once I got to ENV stuff, I'm going to tackle that next.
Test Plan: Ran phabricator normally; introduced fatals and misconfigurations. Grepped for changed symbols.
