Jonny Harris 582ddb82f4 Script Loader: Improve performance of wp_maybe_inline_styles function.
The `wp_maybe_inline_styles` function is called twice on the average page load. On it's second run however, it did not check to see if the style had already been processed on the first run. This resulted in calling `filesize` and `get_file_contents` unnecessarily, which was bad for performance. Now, the loop around the queued styles, checks to see if the source is set to false, meaning it has already been processed. This change also replaces calls to `filesize` with the core function `wp_filesize`, which improves extensibility. 

Props spacedmonkey, flixos90, peterwilsoncc, joemcgill.
Fixes #58394.

The short version:

1. Create a clean MySQL database and user. DO NOT USE AN EXISTING DATABASE or you will lose data, guaranteed.

2. Copy wp-tests-config-sample.php to wp-tests-config.php, edit it and include your database name/user/password.

3. $ svn up

4. Run the tests from the "trunk" directory:
   To execute a particular test:
      $ phpunit tests/phpunit/tests/test_case.php
   To execute all tests:
      $ phpunit

Notes:

Test cases live in the 'tests' subdirectory. All files in that directory will be included by default. Extend the WP_UnitTestCase class to ensure your test is run.

phpunit will initialize and install a (more or less) complete running copy of WordPress each time it is run. This makes it possible to run functional interface and module tests against a fully working database and codebase, as opposed to pure unit tests with mock objects and stubs. Pure unit tests may be used also, of course.

Changes to the test database will be rolled back as tests are finished, to ensure a clean start next time the tests are run.

phpunit is intended to run at the command line, not via a web server.
