Konstantin Obenland c56a8ae0f7 Introducing Site Icon, favicon management for WordPress.
This v1 marries Jetpack's Site Icon module with the Media Modal, reusing code
from the Custom Header admin. For now, the core-provided icons will be limited
to a favicon, an iOS app icon, and a Windows tile icon, leaving `.ico` support
and additional icons to plugins to add.

Props obenland, tyxla, flixos90, jancbeck, markjaquith, scruffian.
See #16434.

* Retrieve paginated link for archive post pages.

* create the paginated links. The 'format' argument is then used for replacing
* the page number. It is however, most likely and by default, to be used on the
* archive post pages.
*
* The 'type' argument controls format of the returned value. The default is
* 'plain', which is just a string with the links separated by a newline
* character. The other possible values are either 'array' or 'list'. The
* 'array' value will return an array of the paginated link list to offer full
* control of display. The 'list' value will place all of the paginated links in
* an unordered HTML list.
*
* The 'total' argument is the total amount of pages and is an integer. The
* 'current' argument is the current page number and is also an integer.
*
* An example of the 'base' argument is "http://example.com/all_posts.php%_%"
* and the '%_%' is required. The '%_%' will be replaced by the contents of in
* the 'format' argument. An example for the 'format' argument is "?page=%#%"
* and the '%#%' is also required. The '%#%' will be replaced with the page
* number.
*
* You can include the previous and next links in the list by setting the
* 'prev_next' argument to true, which it is by default. You can set the
* previous text, by using the 'prev_text' argument. You can set the next text
* by setting the 'next_text' argument.
*
* If the 'show_all' argument is set to true, then it will show all of the pages
* instead of a short list of the pages near the current page. By default, the
* 'show_all' is set to false and controlled by the 'end_size' and 'mid_size'
* arguments. The 'end_size' argument is how many numbers on either the start
* and the end list edges, by default is 1. The 'mid_size' argument is how many
* numbers to either side of current page, but not including current page.
*
* It is possible to add query vars to the link by using the 'add_args' argument
* and see {@link add_query_arg()} for more information.
*
* The 'before_page_number' and 'after_page_number' arguments allow users to
* augment the links themselves. Typically this might be to add context to the
* numbered links so that screen reader users understand what the links are for.
* The text strings are added before and after the page number - within the
