New functions in `media.php`:
* `wp_get_attachment_image_srcset_array()` - Returns an array of image candidate string data used to build a `srcset` value for an attachment given an `$attachement_id` and `$size`.
* `wp_get_attachment_image_srcset()` - Returns the `srcset` value for an attachment given an `$attachement_id` and `$size`.
* `wp_get_attachment_image_sizes()` - Returns the `sizes` value for an attachment given an `$attachement_id` and `$size` and optional arguments used to alter its output.
* `wp_make_content_images_responsive()` - A display filter for adding `srcset` and `sizes` to images embedded in content.
* `wp_img_add_srcset_and_sizes()` - A utility function used by `wp_make_content_images_responsive()` to add `srcset` and `sizes` to a single `<img>` element.
Modifies existing core functions:
* Modify `wp_get_attachment_image()` so the HTML returned for an image includes `srcset` and `sizes`.
* Modify `get_media_embedded_in_content()` (sup, 3.6 leftover) by adding `<img>` to the list of accepted tags that can be matched in content. This is used in `wp_make_content_images_responsive()` to find all of the images embedded in content before passing them off to `wp_img_add_srcset_and_sizes()`.
Tests:
* Add a new factory method to `WP_UnitTest_Factory_For_Attachment` named `create_upload_object()`
* Adds unit tests
* Updates unit tests

The `WP_INSTALLING` constant is a flag that WordPress sets in a number of
places, telling the system that options should be fetched directly from the
database instead of from the cache, that WP should not ping wordpress.org for
updates, that the normal "not installed" checks should be bypassed, and so on.
A constant is generally necessary for this purpose, because the flag is
typically set before the WP bootstrap, meaning that WP functions are not yet
available. However, it is possible - notably, during `wpmu_create_blog()` -
for the "installing" flag to be set after WP has already loaded. In these
cases, `WP_INSTALLING` would be set for the remainder of the process, since
there's no way to change a constant once it's defined. This, in turn, polluted
later function calls that ought to have been outside the scope of site
creation, particularly the non-caching of option data. The problem was
particularly evident in the case of the automated tests, where `WP_INSTALLING`
was set the first time a site was created, and remained set for the rest of the
suite.
The new `wp_installing()` function allows developers to fetch the current
installation status (when called without any arguments) or to set the
installation status (when called with a boolean `true` or `false`). Use of
the `WP_INSTALLING` constant is still supported; `wp_installing()` will default
to `true` if the constant is defined during the bootstrap.

The override is necessary because the `get_term()` call, which fetches the
term object, needs the `'taxonomy'` argument passed to the factory method.
Props dlh.

Tries to get network detection under control by simplifying wpmu_current_site(). It now also pops off each subdomain to find a more general match. Adds unit tests for get_network_by_path() and a new network factory for unit tests.
Much of this is likely to change in 3.9 as more of ms-load.php and ms-settings.php gets hacked to bits.
props jeremyfelt.

There are a few places in core that were preventing this from working by explicity setting `$wpdb->suppress_errors` to `false`. Instead, they should inherit the value that existed before errors were suppressed.
This allows Multisite unit tests to run without explosive database errors, and allows `$wpdb->suppress_errors` to be overridden all the way down the chain.

wp-tests-config.php can/should reside in the root of a develop checkout. `phpunit` should be run from the root.
