Felix Arntz 0514150026 Media: Introduce wp_content_img_tag filter.
This filter allows modifying individual `img` tags within a blob of content that are by default processed by the `wp_filter_content_tags()` function. The addition of this filter facilitates plugins that tweak images to accomplish this goal without re-implementing duplicate content image parser logic, which furthermore can have a negative performance impact due to additional regular expressions.

In addition to the filterable `img` tag, the filter receives the context (typically the function or filter in which the content is parsed) and the attachment ID. The latter may be 0, in case the image is not an attachment (for example when it is an external image URL).

Fixes #55347.

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.
