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 function encapsulates the existing `subdirectory_reserved_names` filter and reduces the maintenance burden of keeping the value of (currently) two instances of the same hook in sync.

A number of the HTTP external tests can inconstantly fail. As the HTTP API is one that doesn't change often, this failure creates noise. With the goal of increasing the signal from the unit tests, these tests are now skipped if they timeout. A notice is added when running the external http tests so that the developer knows what skipped tests may mean here.

It should be the time at which the post was written, but it was never because of the missing `$parent` argument.

Adds unit tests for `WP_Customize_Setting::save()` (and `WP_Customize_Setting::update()`), along with the actions `customize_update_{$type}`, and `customize_save_{$id_base}` which they trigger.

This brings it closer to the width of the input so there is less jumping around of buttons. We can afford the space now that other buttons in the space are typically no longer there.

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.

Assigns the `wp-activate-container` and `wp-signup-container` to the container inside `#signup-container` on each. This container already existed in `wp-signup.php` and is new in `wp-activate.php`.

After some discussion, it was decided that Multisite vs single site context can just as easily be derived using available functions like `is_network_admin()`, `get_current_screen()`, etc., rendering the second parameter moot. The hook was introduced in [34796].

This function attempts to read from the relationship cache, and uses any data
it finds. If it finds no data, it does a query for the data it needs. Since we
are going to the trouble to query for the relationships, and since we are
already using cached data when available, let's go ahead and cache it for
later use.

Renames `reset_permalinks()` to `set_permalink_structure()` (mimicking `$wp_rewrite->set_permalink_structure()`) and allows it to accept an optional permalink structure. In this way, we can double dip using it to both set and reset the permalink structure from anywhere.
Removes alot of duplicated code from tests.

`wp_insert_term()` doesn't allow the creation of a term when the term `name`
is the same as another term in the same hierarchy level of the same taxonomy.
Previously, this duplicate check used `get_term_by( 'name' )`, which uses the
database collation to determine sameness. But common collations do not
distinguish between accented and non-accented versions of a character. As a
result, it was impossible to create a term 'Foo' if a sibling term with an
accented character existed.
We address this problem by using `get_terms()` to do the duplicate check. This
query returns all potentially matching terms. We then do a stricter check
for equivalence in PHP, before determining whether one of the matches is
indeed a duplicate.
