Summary:
People have occasionally complained about phabricator being slow. We have
the access log to look at to see when slowness happens, but it doesn't tell
us much about why it happened. Since it's usually a sporadic issue that's
reported, it's hard to reproduce and then profile. This change will allow us
to collect sampled profiles so we can look at them when slowness occurs.
Test Plan:
checking that sampling works correctly:
- set rate to 0; do several page loads; check no new entries in table
- set rate to 1; check that there's a new row in the table for each page load
- set rate to 10; check that some requests write to table and some don't
check new ui for samples:
- load /xhprof/list/all/, see a list with a lot of samples
- load /xhprof/list/sampled/, see only sampled runs
- load /xhprof/list/manual/, see only non-sampled runs
- load /xhprof/list/my-runs/, se only my manual runs

Summary:
- `kill_init.php` said "Moving 1000 files" - I hope that this is not some limit in `FileFinder`.
- [src/infrastructure/celerity] `git mv utils.php map.php; git mv api/utils.php api.php`
- Comment `phutil_libraries` in `.arcconfig` and run `arc liberate`.
NOTE: `arc diff` timed out so I'm pushing it without review.
Test Plan:
/D1234
Browsed around, especially in `applications/repository/worker/commitchangeparser` and `applications/` in general.

Summary: Ideally there should be a "send epriestley this profile" button but this is a reasonable step forward. Add a "download .xhprof profile" button to profiles, since walking through these things remotely is pretty awkward. Also expand "Excl" and "Incl" acronyms.
Test Plan: Clicked download button.

Summary:
These are all unambiguously unextensible. Issues I hit:
- Maniphest Change/Diff controllers, just consolidated them.
- Some search controllers incorrectly extend from "Search" but should extend from "SearchBase". This has no runtime effects.
- D1836 introduced a closure, which we don't handle correctly (somewhat on purpose; we target PHP 5.2). See T962.
Test Plan: Ran "testEverythingImplemented" unit test to identify classes extending from `final` classes. Resolved issues.

Summary:
While sort of gross, this seems fairly reasonable overall? I guess?
(This patch clearly does more good than harm, although it could just do the good
without the harm.)
Test Plan: Clicked XHProf links from the frame and from the /xhprof/ tool.

Summary:
- Services: Show summary panel of total service call costs and relative page weight.
- Services: Add "Analyze Query Plans" button, which issues EXPLAIN for each query and flags problems.
- XHPRof: iframe the profile.
Test Plan: Used the new query plan analysis to find missing keys causing table scans, see D627.
