vrana ef85f49adc Delete license headers from files
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.

/**
* NOTE: This is an ADVANCED feature that improves performance but adds a lot
* of complexity! This is only suitable for production servers because workers
* won't pick up changes between when they spawn and when they handle a request.
*
* Phabricator spends a significant portion of its runtime loading classes
* and functions, even with APC enabled. Since we have very rigidly-defined
* rules about what can go in a module (specifically: no side effects), it
* is safe to load all the libraries *before* we receive a request.
*
* Normally, SAPIs don't provide a way to do this, but with a patched PHP-FPM
* SAPI you can provide a warmup file that it will execute before a request
* is received.
*
* We're limited in what we can do here, since request information won't
* exist yet, but we can load class and function definitions, which is what
* we're really interested in.
*
* Once this file exists, the FCGI process will drop into its normal accept loop
* and eventually process a request.
