In PHP 5.3.0, `is_a()` is no longer deprecated, and will therefore no longer throw `E_STRICT` warnings.
To avoid warnings in PHP < 5.3.0, convert all `is_a()` calls to `$var instanceof WP_Class` calls.
`instanceof` does not throw any error if the variable being tested is not an object, it simply returns `false`.
Props markoheijnen, wonderboymusic.

Note that this does not fix issues related to comment quick edit. Internal linking also continues to use the `.alternate` class for now. IE8 and below gracefully degrade by not having zebra striping.
There is some hoop jumping with adding an extra table row to maintain zebra striping during quick edit. Documenting that here for future reference; it is also in the inline documentation.
fixes#30981 and #26060. see #25060.

Up to this point, various core elements' DocBlocks incorrectly included an `@internal` tag as a means for skipping the parsing process. When paired with a description (inline or otherwise), `@internal` is a valid tag meant to provide internal-only context, but not necessarily to skip parsing the entire element.

When editing a site, if `home` and `siteurl` are checked to be updated along with a site's domain and path, they should receive the results of any modifications in `update_blog_details()` rather than trusting the POST data.
Previously, it was possible to save a value without a leading slash on the path, causing an invalid URL to be stored.
Props earnjam.

[29863] made the corresponding change in `term_exists()`. Failure to change the
default value in `category_exists()` meant that an unspecified value for
`$parent` would limit results to top-level categories.
Includes unit tests and corrected function documentation.
Props hissy.

* In [28481], `$admin_header_callback` and `$admin_image_div_callback` were set to `private` based on their erroneous `@param` values
* `$admin_header_callback` and `$admin_image_div_callback` are used as hook callbacks - as such, they must be `public`
* In [28521] and [28524], magic methods were added for back-compat
* Currently, there are 4 properties marked `private`: `$uploaded_headers`, `$default_headers`, `$page`, and `$updated` - `$page` and `$uploaded_headers` are never used and `$updated` was added by me in [30187] during 4.1. `$default_headers` does not necessarily need to be `private`
Set `$admin_header_callback` and `$admin_image_div_callback` to `public`.
Remove the `$page` property - it duplicated the `$page` local var and is referenced/used nowhere.
Remove the `$uploaded_headers` property - it is used nowhere and is dead code.
Set `$default_headers` to `public`.
Remove the magic methods - they were beyond overkill and rendered moot by the above changes.

* `get_permalink( $post_ID )` can return `false`, set it to a variable and check it
* Using the variable allows us to replace 11 separate calls to `get_permalink( $post_ID )` in the file
* These notices were triggered by the potential for `false` to be passed to `esc_url()`

* In `->init()`, don't check `current_user_can()` since `add_theme_page()` will return `false` immediately if the cap check fails.
* Bail if `add_theme_page()` returns `false`
* `wp_check_filetype_and_ext()` doesn't need a 3rd param, it already defaults to `null`. Passing `false` would fail a strict check.
