9b92304fd1 Database: Restore numbered placeholders in wpdb::prepare().
[41496] removed support for numbered placeholders in queries send through `wpdb::prepare()`, which, despite being undocumented, were quite commonly used.

This change restores support for numbered placeholders (as well as a subset of placeholder formatting), while also adding extra checks to ensure the correct number of arguments are being passed to `wpdb::prepare()`, given the number of placeholders.

Merges [41662], [42056] to the 3.9 branch.
See #41925.

/**
* Prepares a SQL query for safe execution. Uses sprintf()-like syntax.
*
* The following directives can be used in the query format string:
* The following placeholders can be used in the query string:
* %d (integer)
* %f (float)
* %s (string)
* %% (literal percentage sign - no argument needed)
*
* All of %d, %f, and %s are to be left unquoted in the query string and they need an argument passed for them.
* Literals (%) as parts of the query must be properly written as %%.
* All placeholders MUST be left unquoted in the query string. A corresponding argument MUST be passed for each placeholder.
*
* This function only supports a small subset of the sprintf syntax; it only supports %d (integer), %f (float), and %s (string).
* Does not support sign, padding, alignment, width or precision specifiers.
* Does not support argument numbering/swapping.
* For compatibility with old behavior, numbered or formatted string placeholders (eg, %1$s, %5s) will not have quotes
* added by this function, so should be passed with appropriate quotes around them for your usage.
*
* May be called like {@link http://php.net/sprintf sprintf()} or like {@link http://php.net/vsprintf vsprintf()}.
* Literal percentage signs (%) in the query string must be written as %%. Percentage wildcards (for example,
* to use in LIKE syntax) must be passed via a substitution argument containing the complete LIKE string, these
* cannot be inserted directly in the query string. Also see {@see esc_like()}.
*
* Both %d and %s should be left unquoted in the query string.
* Arguments may be passed as individual arguments to the method, or as a single array containing all arguments. A combination
* of the two is not supported.
*
* <code>
* wpdb::prepare( "SELECT * FROM `table` WHERE `column` = %s AND `field` = %d", 'foo', 1337 )
* wpdb::prepare( "SELECT DATE_FORMAT(`field`, '%%c') FROM `table` WHERE `column` = %s", 'foo' );
* </code>
* Examples:
* $wpdb->prepare( "SELECT * FROM `table` WHERE `column` = %s AND `field` = %d OR `other_field` LIKE %s", array( 'foo', 1337, '%bar' ) );
* $wpdb->prepare( "SELECT DATE_FORMAT(`field`, '%%c') FROM `table` WHERE `column` = %s", 'foo' );
