An excessive amount of autoloaded options is a common cause for slow database responses, sometimes caused by very large individual autoloaded options. As it is not mandatory to provide an autoload value when adding an option to the database, it tends to be ignored, which in combination with a default value of "yes" and lack of documentation can lead to the aforementioned problem.
This changeset enhances the option autoloading behavior in several ways:
* Update the function documentation to encourage the use of boolean `true` or `false` to explicitly provide an autoload value for an option.
* Use new string values `on` and `off` for explicitly provided values stored in the database, to distinguish them from `yes` and `no`, since `yes` does not allow determining whether it was set intentionally by the developer or only as a default.
* Effectively deprecate the values `yes` and `no`. They are still supported for backward compatibility, but now discouraged.
* Use `null` as new default autoload value for `add_option()`. If the developer does not provide an explicit value, this will now trigger WordPress logic to determine an autoload value to use:
* If WordPress determines that the option should not be autoloaded, it is stored in the database as `auto-off`. As part of this changeset, the single heuristic introduced for that is to check whether the option size is larger than a threshold of 150k bytes. This threshold is filterable via a new `wp_max_autoloaded_option_size` filter.
* If WordPress determines that the option should be autoloaded, it is stored in the database as `auto-on`. No logic to make such a decision is introduced as part of this changeset, but a new filter `wp_default_autoload_value` can be used to define such heuristics, e.g. by optimization plugins.
* If WordPress cannot determine whether or not to autoload the option, it is stored in the database as `auto`.
* This effectively means that any option without an explicit autoload value provided by the developer will be stored with an autoload value of `auto`, unless the option's size exceeds the aforementioned threshold. Options with a value of `auto` are still autoloaded as of today, most importantly for backward compatibility. A new function `wp_autoload_values_to_autoload()` returns the list of autolaod values that dictate for an option to be autoloaded, and a new filter `wp_autoload_values_to_autoload` can be used to alter that list.
These behavioral changes encourage developers to be more mindful of autoloading, while providing WordPress core and optimization plugins with additional control over heuristics for autoloading options where no explicit autoload value was provided.
At the same time, the changes are fully backward compatible from a functionality perspective, with the only exception being that very large options will now no longer be autoloaded if the developer did not explicitly request for them to be autoloaded. Neither WordPress core nor plugins are able to override an explicitly provided value, which is intentional to continue giving developers full control over their own options.

A collection of fixes for `wp_prime_option_caches()`:
* cache arrays and objects in their serialized form for consistency with `get_option()` and `wp_load_alloptions()`
* prevent repeat database queries for falsey and known non-existent options (notoptions)
Additional tests for `wp_prime_option_caches()` to ensure:
* additional database queries are not made repriming options (known, known-unknown and alloptions)
* cache is primed consistently
* `get_option()` returns a consistent value regardless of how it is primed
* database queries do not contain earlier primed options
* `get_option` does not prime the cache when testing the cache has been successfully primed
Fixes a test for `wp_prime_option_caches_by_group()` to ensure `get_option` does not prime the cache when testing the cache has been successfully primed.

Previously, in the update_network_option function, strict comparisons between old and new values could erroneously trigger updates in cases where there was no actual change in values. Building upon the groundwork laid in #22192, this commit introduces the use of the _is_equal_database_value function to accurately compare values before initiating any database updates. This change ensures consistency between the behaviors of `update_option` and `update_network_option`.
Furthermore, we have incorporated similar workarounds that were previously implemented in [56717]. These changes ensure that the raw version of network option values is considered in the comparisons, enhancing the overall reliability of the update process.

Prior to this change, a strict comparison between the old and new database value could lead to a false negative, since database values are generally stored as strings. For example, passing an integer to `update_option()` would almost always result in an update given any existing database value for that option would be that number cast to a string.
This changeset adjusts the logic to perform an intentional "loose-y" comparison by casting the values to strings. Extensive coverage previously added in [56648] provides additional confidence that this does not introduce any backward compatibility issues.

In the get_option function, a cache lookup for the notoptions key is performed, which stores an array of keys for options known not to exist. This optimization prevents repeated database queries when certain options are requested. However, the cache lookup for notoptions was conducted before checking if the requested option exists in the cache. Given that it's more likely that the option does exist, this commit reorders the checks to first verify the option's existence in the cache before confirming its absence. This adjustment reduces redundant queries and also eliminates an unnecessary cache lookup, improving overall performance.

This function accepts an associative array of option names and their autoload values to set, and it will update those values in the database in bulk, only for those options where the autoload field is not already set to the given value.
Two wrapper functions for ease of use accompany the new main function:
* `wp_set_options_autoload( $options, $autoload )` can be used to set multiple options to the same autoload value.
* `wp_set_option_autoload( $option, $autoload )` can be used to set the autoload value for a single option.
All of these functions allow changing the autoload value of an option, which previously has only been possible in combination with updating the value. This limitation prevented some relevant use-cases: For example, a plugin deactivation hook could set all of its options to not autoload, as a cleanup routine, while not actually deleting any data. The plugin's activation hook could then implement the reverse, resetting those options' autoload values to the originally intended ones for when using the plugin.

WordPress's `get_option()` function generally relies on making individual database requests for each option, however with the majority of options (in most cases) being autoloaded, i.e. fetched once with a single database request and then stored in (memory) cache.
As part of a greater effort to reduce the amount of options that are unnecessarily autoloaded, this changeset introduces an alternative way to retrieve multiple options in a performant manner, with a single database request. This provides a reasonable alternative for e.g. plugins that use several options which only need to be loaded in a few specific screens.
Specifically, this changeset introduces the following functions:
* `prime_options( $options )` is the foundation to load multiple specific options with a single database request. Only options that aren't already cached (in `alloptions` or an individual cache) are retrieved from the database.
* `prime_options_by_group( $option_group )` is a convenience wrapper function for the above which allows to prime all options of a specific option group (as configured via `register_setting()`).
* `get_options( $options )` is another wrapper function which first primes the requested options and then returns them in an associative array, calling `get_option()` for each of them.

The `wp_user_settings()` function calls the PHP native `setcookie()` function, the fifth parameter of which is the ''optional'' `$domain` parameter which expects a `string`.
A parameter being optional, however, does not automatically make it nullable.
As of PHP 8.1, passing `null` to a non-nullable PHP native function will generate a deprecation notice.
In this case, this function call yielded a `setcookie(): Passing null to parameter #5 ($domain) of type string is deprecated` notice.
Changing the `null` to an empty string fixes this without a backward compatibility break.

In all four of the `get_option()`, `add_option()`, `update_option()` and `delete_option()` functions, the `$option` parameter (i.e. the option name) is passed to the PHP native `trim()` function without prior input validation.
In PHP 8.1, this could lead to a `trim(): Passing null to parameter #1 ($string) of type string is deprecated` for each of these functions.
`trim()`:
- expects a text string and is only useful when ''passed'' a text string as no other variable type can contain whitespace.
- will always return a `string`, which means that in practice for any non-string values passed, it would effectively function as a type cast to string.
This commit:
- Adds a check to verify the `$option` name is a scalar before processing it with `trim()`.
- The "type cast" behavior is maintained.
- If the given `$option` name is not a scalar, such as `null`, the fix prevents the PHP 8.1 deprecation notice.
- Tests are added for valid but undesired option names to safeguard against regressions.
This issue is already covered by:
- the existing `Tests_Option_Option::test_bad_option_names()` test group.
- the new `test_valid_but_undesired_option_names()` tests.
