Summary:
For some time, we've stopped the profiler twice when it was invoked by the sampling mechanism. The first time it actually stops, and we write a profile. The second time it hadn't been started, so it returns empty and we write an invalid profile.
Instead, keep track of whether it is running or not, and don't stop it a second time.
Ref T2870.
Test Plan: Set sample rate to 1-in-3, observed valid sample profiles generate.

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).
Depends on D5532. Fixes T2860. Ref T2870.
Test Plan: Disabled access log, verified XHProf writes occurred correctly.

Summary:
- Separate the ideas of "requested" (explicit user request) vs "started" (user request or sampling).
- Move this code out of index.php into the XHProf stuff (general effort to make index.php smaller).
Test Plan:
Verified that profiling still works, and profiling extends to ajax requests.
Set sampling rate to 2, saw 50% samples.
Looked at database, saw sampling data populating properly.

Summary: Route all `$_SERVER['HTTP_...']` stuff through AphrontRequest (it would be nice to make this non-static, but the stack is a bit tangled right now...)
Test Plan: Verified CSRF and cascading profiling. `var_dump()`'d User-Agent and Referer and verified they are populated and returned correct values when accessed. Restarted server to trigger setup checks.

Summary: If a page is profiled, add an "X-Phabricator-Profiler" header to all Ajax requests, and profile those too.
Test Plan: Profiled a page, checked Darkconsole, saw profiles for everything.

Summary:
This commit doesn't change license of any file. It just makes the license implicit (inherited from LICENSE file in the root directory).
We are removing the headers for these reasons:
- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.
This change is approved by Alma Chao (Lead Open Source and IP Counsel at Facebook).
Test Plan: Verified that the license survived only in LICENSE file and that it didn't modify externals.

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:
Currently, it's hard to debug performance issues on POST pages. Add flags to stop redirects and always collect profiles.
Also fix an issue with "all" profiles. This feature is mostly just for profiling DarkConsole itself and is rarely used, I think it's been broken for some time. There's no way to get to it with the UI.
NOTE: Some JS workflows don't stop on redirect because they use JS/AJAX redirects.
Test Plan: Enabled options, browsed, got stopped on redirects and had profiles generated. Disabled options and verified redirects and profiles work normally.

Summary:
- all search boxes are now jump navs (old functionality retained if none
of the jump nav patterns match)
- added global keyboard shortcut '/' to focus the search box in the upper
right
Test Plan:
- pressed '/' and noticed the search box gains keyboard focus
- triggered jump nav functionality from search box and saw it worked
- did a search which did not match a jump nav pattern and saw it worked
(and searched in the selected context)
NOTE: The search box on the /search/ page is also changed to have jump
nav functionality. Old functionality is not impared. Still, this may not
be desirable.
