Why:
* Maintenance scripts in core have bolierplate code that is
added before and after the class to allow directly running
the maintenance script.
* Running the maintenance script directly has been deprecated
since 1.40, so this boilerplate code is only to support a now
deprecated method of running maintenance scripts.
* This code cannot also be marked as covered, due to PHPUnit
not recognising code coverage for files.
* Therefore, it is best to ignore this boilerplate code in code
coverage reports as it cannot be marked as covered and also
is for deprecated code.
What:
* Wrap the boilerplate code (requiring Maintenance.php and then
later defining the maintenance script class and running if the
maintenance script was called directly) with @codeCoverageIgnore
comments.
* Some files use a different boilerplate code, however, these
should also be marked as ignored for coverage for the same
reason that coverage is not properly reported for files.

And start using them instead of wfGetDB(), LB/LBF connection methods or
worse, $this->getDB().
$this->getDB() reuses the database object regardless of whether you're
calling a replica or primary, leading to returning a replica on a
primary and other way around.

Maintenance class provides a method for getting a fresh reference
of the MW services container instance. Let's make use of these in
maintenance scripts now that we have it.
NOTE: There are still some static methods like in refreshLinks.php
that makes use of services that we can't use this method for now.

LocalFile::lock() held an explicit DB transaction open while a
potentially slow file backend operation was in progress, causing
production errors.
Instead, protect write operations with non-blocking locks. If a file is
locked, report the failure to the user. Like an edit conflict, informing
the user is appropriate in most cases. For example, if two admins try to
delete the same file at the same time, only one should succeed, and the
second does not need to wait for the first.
In upgradeRow(), locks were used to protect operations which read from a
file and write the result back to the database. The lock was supposed
to prevent overwriting of fresh data with stale data. Use a timestamp
check instead.

Queries that query a value "1" are expected to return either
that "1" (possibly as a string), or false. It's safe to simply
cast this to bool and use it as it is.
Queries for COUNT(*) are expected to return that number,
possibly as a string. It's not possible for such a query to
return false. And even if, casting to 0 is fine.
I found an existing code style where the table name and the
"1" are on the same line as the selectField() method name, and
applied it to all similar queries.

Add transaction methods to complement getDB().
This makes it easy to grep for direct begin()/commit()
calls to IDatabase by having script use their own
wrapper. Maintenance scripts are one of the few places
that can (and need to) use begin/commit instead of the
start/end atomic methods.
Eventually, there should be almost no direct callers
and those methods can be made stricter about throwing
errors on nested calls.

Some of deleteArchivedFiles.php and deleteArchivedRevisions.php were
split off to deleteArchivedFiles.inc and deleteArchivedRevisions.inc
respectively in r62948 (04b2413aac) for use in tests.
The tests no longer use those methods, so I moved them back and inlined
them into execute(). I also did some minor cleanup -- changing direct
calls to tableName() and query() to use query builder functions and
clarifying/fixing some of the logic that was in deleteArchivedFiles.inc.

Follows-up I1343872de7, Ia533aedf63 and I2df2f80b81.
Also updated usage in text in documentation and the
installer LocalSettingsGenerator.
Most of them were handled by this regex:
- find: (require|include|require_once|include_once)\s*\(\s*(.+?)\s*\)\s*;$
- replace: $1 $2;

Squiz.WhiteSpace.LanguageConstructSpacing:
Language constructs must be followed by a single space;
expected "require_once expression" but found
"require_once(expression)"
It is a keyword (e.g. like `new`, `return` and `print`). As
such the parentheses don't make sense.
Per our code conventions, we use a space after keywords like
these. We appeared to have an unwritten exception for `require`
that doesn't make sense. About 60% of require/include usage
was missing the space and/or had superfluous parentheses.
It is as silly as print("foo") or return("foo"), it works
because keywords have no significance for whitespace between
it and the expression that follows, and since experessions can
be wrapped in parentheses for clarity (e.g. when doing string
concatenation or mathematical operations) the parenthesis
before and after basiclaly just ignored.

We can now do this since we finally switched to PHP 5.3 for MW 1.20 and get rid of the silly dirname(__FILE__) stuff :)

Until now, we relied on setting MW_NO_SETUP which was a) hacky, b) irreversable, and c) likely to be forgotten if you didn't use one of the wrappers like runChild().
Instead, move the freaky magic to doMaintenance and have *it* check if it's in a specific call stack that indicates this is being run from the file scope and should be executed. Rename DO_MAINTENANCE to RUN_MAINTENANCE_IF_MAIN so it's nice and clear what magic happens behind the require_once().
* Docs have been updated to indicate the standard on how to write maintenance scripts (MW.org docs will follow) Have ported vast majority of maintenance scripts to new format. Remaining ones (mostly FiveUpgrade-related) are a bit more tricky. commandLine.inc is untouched for now. Many have gotten code-style updates as well. Deleted .inc files were only used by their .php counterparts, and have been merged into single files.
* (bug 11867) Lock error on redirect table when running orphans.php
* (bug 16322) Allow maintenance scripts to accept DB user/pass over input or params
* (bug 18566) Maintenance script to un/protect pages
* initStats overhaul, now uses class SiteStatsInit. Also fixes bug 18930
Doxygen documentation update:
* Changed alls @addtogroup to @ingroup. @addtogroup adds the comment to the group description, but doesn't add the file, class, function, ... to the group like @ingroup does. See for example http://svn.wikimedia.org/doc/group__SpecialPage.html where it's impossible to see related files, classes, ... that should belong to that group.
* Added @file to file description, it seems that it should be explicitely decalred for file descriptions, otherwise doxygen will think that the comment document the first class, variabled, function, ... that is in that file.
* Removed some empty comments
* Removed some ?>
Added following groups:
* ExternalStorage
* JobQueue
* MaintenanceLanguage
One more thing: there are still a lot of warnings when generating the doc.
