Gary Pendergast 4d3a84aa9f Code Modernisation: Introduce the spread operator in `wpdb::prepare()`.
Rather than relying `func_get_args()` to retrieve arbitrary function arguments, we can now use the spread operator to assign them directly to a variable.

Props jrf.

Gary Pendergast abcbee954f Coding Standards: Fix instances of `WordPress.PHP.NoSilencedErrors.Discouraged`.
Noteable changes:
- The `magic_quotes_runtime` and `magic_quotes_sybase` settings were removed in PHP 5.4, so no longer need to be set.
- Some functions that use external libraries can generate errors that can't be tested for, so are globally allowed to silence errors.
- Quite a few functions would cause errors if `safe_mode` was set. This setting was removed in PHP 5.4.
- Only a handful of `header()` calls needed corresponding `headers_sent()` checks for unit tests to pass, but more may need to be added as the nightlies builds are tested.

Gary Pendergast 56c162fbc9 Coding Standards: Upgrade WPCS to 1.0.0
WPCS 1.0.0 includes a bunch of new auto-fixers, which drops the number of coding standards issues across WordPress significantly. Prior to running the auto-fixers, there were 15,312 issues detected. With this commit, we now drop to 4,769 issues.

This change includes three notable additions:
- Multiline function calls must now put each parameter on a new line.
- Auto-formatting files is now part of the `grunt precommit` script. 
- Auto-fixable coding standards issues will now cause Travis failures.

Felix Arntz 176a289050 Multisite: Introduce metadata for sites.
A new global multisite table `wp_blogmeta` is added to the database schema, and a set of `*_site_meta()` API functions are introduced.

The implementation fails gracefully when the new table is not yet available, which may happen especially shortly after the core update, before the network has been upgraded to the new database schema. The presence of the table is detected once and stored as a global setting on the main network.

Core does not yet use site metadata, but there are several use-cases to be implemented or explored in the near future, and it allows plugins to extend sites with arbitrary data, which will come in particularly handy with the upcoming REST API endpoint for sites.

Drew Jaynes 0860bb2771 Docs: Remove `@access` notations from method DocBlocks in wp-includes/* classes.
Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.

See #41452.

Gary Pendergast 7329283f7e Database: Add support for `LIKE`-escaped tables in `::get_table_from_query()`.
The `SHOW TABLES LIKE` query can be used to search for tables that match a pattern, `wp\_123\_%`, for example. While this isn't the name of an actual table, the `wp_123_` prefix can be used by database drop-ins to direct the query correctly. This change removes the escaping and `%` modifier, to provide this usable prefix.

Props andy, pento.

Gary Pendergast 2dee7cdffc Database: Fall back to `utf8` when `utf8mb4` isn't supported.
Sometimes, `DB_CHARSET` will be set to `utf8mb4`, even if the current setup doesn't support `utf8mb4`. After [38442], this can cause significant character set failures, causing the connection to fall back to `latin1`.

Instead of doing this, we now check that the connection supports `utf8mb4` before trying to use it, and fall back to `utf8` when we need to.

Fixes #37982 for trunk.
