Sergey Biryukov 5cbf7edcc8 Login and Registration: Rename is_login_screen() function to is_login().
As the function can be used in a variety of contexts, the `_screen` suffix may not always be appropriate.

This commit aims to reduce confusion by renaming the newly added `is_login_screen()` function to `is_login()`, which better aligns with `is_admin()` and the related `is_*_admin()` function family.

While it does not save a lot of lines of code, this function aims to save developers some time that would otherwise be spent investigating the most reliable way to determine whether the current request is for the login screen.

Implementation details:
* By checking `wp_login_url()`, the function accounts for custom login locations set via the `login_url` filter.
* By checking `$_SERVER['SCRIPT_NAME']` directly, instead of `did_action( 'login_form_login' )` or `$pagenow` global, the function can work as early as possible, for example in a must-use plugin.

Follow-up to [53884].

Props azaozz.

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.
