Sergey Biryukov 84e9601e5a Code Modernization: Replace usage of `substr()` with `str_starts_with()` and `str_ends_with()`.
`str_starts_with()` and `str_ends_with()` were introduced in PHP 8.0 to perform a case-sensitive check indicating if the string to search in (haystack) begins or ends with the given substring (needle).

WordPress core includes a polyfill for these functions on PHP < 8.0 as of WordPress 5.9.

This commit uses `str_starts_with()` and `str_ends_with()` in core files where appropriate:
* `$needle === substr( $string, 0, $length )`, where `$length` is the length of `$needle`, is replaced with `str_starts_with( $haystack, $needle )`.
* `$needle === substr( $string, $offset )`, where `$offset` is negative and the absolute value of `$offset` is the length of `$needle`, is replaced with `str_ends_with( $haystack, $needle )`.

This aims to make the code more readable and consistent, as well as better aligned with modern development practices.

Sergey Biryukov 1ce5dc7444 Code Modernization: Replace usage of `strpos()` with `str_contains()`.
`str_contains()` was introduced in PHP 8.0 to perform a case-sensitive check indicating if the string to search in (haystack) contains the given substring (needle).

WordPress core includes a polyfill for `str_contains()` on PHP < 8.0 as of WordPress 5.9.

This commit replaces `0 === strpos( ... )` with `str_starts_with()` in core files, making the code more readable and consistent, as well as improving performance.

While `strpos()` is slightly faster than the polyfill on PHP < 8.0, `str_starts_with()` is noticeably faster on PHP 8.0+, as it is optimized to avoid unnecessarily searching along the whole haystack if it does not find the needle.

Felix Arntz de505f0eac Formatting: Improve performance of `esc_url()`.
This changeset indirectly improves performance of the commonly used `esc_url()` function by optimizing the low-level function `wp_kses_bad_protocol()` for the by far most common scenarios, which are URLs using either the `http` or `https` protocol.

For this common scenario, the changeset now avoids the `do while` loop. While for a single call to the `esc_url()` function the performance wins are negligible, given that `esc_url()` is often called many times in one page load, they can add up, making this a worthwhile improvement.

Sergey Biryukov 613091bce5 Code Modernization: Rename parameters that use reserved keywords in `wp-includes/kses.php`.
While using reserved PHP keywords as parameter name labels is allowed, in the context of function calls using named parameters in PHP 8.0+, this will easily lead to confusion. To avoid that, it is recommended not to use reserved keywords as function parameter names.

This commit:
* Renames the `$string` parameter to `$content` in:
 * `wp_kses()`
 * `wp_kses_hook()`
 * `wp_kses_split()`
 * `wp_kses_split2()`
 * `wp_kses_bad_protocol()`
 * `wp_kses_no_null()`
 * `wp_kses_stripslashes()`
 * `wp_kses_bad_protocol_once()`
 * `wp_kses_normalize_entities()`
 * `wp_kses_decode_entities()`
* Renames the `$string` parameter to `$attr` in:
 * `wp_kses_one_attr()`
 * `wp_kses_html_error()`
* Renames the `$match` parameter to `$matches` in:
 * `_wp_kses_split_callback()`
 * `_wp_kses_decode_entities_chr()`
 * `_wp_kses_decode_entities_chr_hexdec()`
* Renames the `$string` parameter to `$scheme` in `wp_kses_bad_protocol_once2()`.

Sergey Biryukov 89e665383f KSES: Display a notice if any of the required globals are not set.
When using the `CUSTOM_TAGS` constant, these global variables should be set to arrays:

* `$allowedposttags`
* `$allowedtags`
* `$allowedentitynames`
* `$allowedxmlentitynames`

This commit aims to improve developer experience by displaying a more helpful message to explain a PHP fatal error further in the code if any of these globals are either not set or not an array.

Note Using `CUSTOM_TAGS` is not recommended and should be considered deprecated. The `wp_kses_allowed_html` filter is more powerful and supplies context.

Peter Wilson 2d944ca1d9 KSES: Allow attributes to be restricted via callbacks.
Add callback validation to HTML tag attributes for increased flexibility over an array of values only.

In `object` tags, validate the `data` attribute via a callback to ensure it is a PDF and matches the `type` attribute. This prevents mime type mismatches in browsers.

Gary Pendergast 2c3205bb84 KSES: Add options for restricting tags based upon their attributes.
This change adds two now attribute-related config options to KSES:
- An array of allowed values can be defined for attributes. If the attribute value doesn't fall into the list, the attribute will be removed from the tag.
- Attributes can be marked as required. If a required attribute is not present, KSES will remove all attributes from the tag. As KSES doesn't match opening and closing tags, it's not possible to safely remove the tag itself, the safest fallback is to strip all attributes from the tag, instead.

Included with this change is an implementation of these options, allowing the `<object>` tag to be stored in posts, but only when it has a `type` attribute set to `application/pdf`.
