Storing the user name or IP in every row in large tables like revision
and logging takes up space and makes operations on these tables slower.
This patch begins the process of moving those into one "actor" table
which other tables can reference with a single integer field.
A subsequent patch will remove the old columns.

Clean up use of @codingStandardsIgnore
- @codingStandardsIgnoreFile -> phpcs:ignoreFile
- @codingStandardsIgnoreLine -> phpcs:ignore
- @codingStandardsIgnoreStart -> phpcs:disable
- @codingStandardsIgnoreEnd -> phpcs:enable
For phpcs:disable always the necessary sniffs are provided.

Importing revisions in MediaWiki has long been weird: if the username on
the imported revision exists locally it's automatically attributed to
the local user, while if the name does not exist locally we wind up with
revision table rows with rev_user = 0 and rev_user_text being a valid
name that someone might later create. "Global" blocks too create rows
with ipb_by = 0 an ipb_by_text being a valid name.
The upcoming actor table change, as things currently stand, would
regularize that a bit by automatically attributing those imported
revisions to the newly-created user. But that's not necessarily what we
actually want to happen. And it would certainly confuse CentralAuth's
attempt to detect its own global blocks.
Thus, this patch introduces "interwiki" usernames that aren't valid for
local use, of the format "iw>Example".[1] Linker will interpret these
names and generate an appropriate interwiki link in history pages and
the like, as if from wikitext like `[[iw:User:Example]]`.
Imports for non-existant local users (and optionally for existing local
users too) will credit the edit to such an interwiki name. There is also
a new hook, 'ImportHandleUnknownUser', to allow extension such as
CentralAuth to create local users as their edits are imported.
Block will no longer accept usable-but-nonexistent names for 'byText' or
->setBlocker(). CentralAuth's global blocks will be submitted with an
interwiki username (see Ieae5d24f9).
Wikis that have imported edits or CentralAuth global blocks should run
the new maintenance/cleanupUsersWithNoId.php maintenance script. This
isn't done by update.php because (1) it needs an interwiki prefix to use
and (2) the updater can't know whether to pass the `--assign` flag.
[1]: '>' was used instead of the more usual ':' because WMF wikis have
many existing usernames containing colons.
