(bug 1) doc for SiteConfiguration

SiteConfiguration was lacking some basic example and a very basic
introduction.

(bug 36839) Use mb_check_encoding() if available.

This is not a real fix for the cause of the bug (which is a
pcre.recursion_limit that is far too low), but I do wonder
about the efficiency of using a regexp to test for valid
UTF-8 encoding. After all the regexp has to be compiled first
into a state machine.

Patch set 2: Php unit test for Language.checkTitleEncoding
Patch set 3: benchmark
Patch set 4: add benchmark for non-capturing subgroup in regexp, and
since that's faster than a capturing subgroup, use it in
checkTitleEncoding() in the regexp branch.
Patch set 5: use Tim's suggestion (once-only pattern) in the regexp
branch. Also add to benchmark.

PHP >= 5.4.0 started taking advantage of $limit optimization of wfDebugBacktrace(),
which we weren't treating right.

* $limit in wfDebugBacktrace() is the number of returned frames,
we thus need to take into account the wfDebugBacktrace() frame, which
is sliced from debug_backtrace().

* wfGetCaller() needs to add a level for itself.

* MWDebug::warning() was logging itself as the warning issuer,
which is useless (the call a few lines before was right, though)
MWDebugTest.php changed accordingly.

* Removed double call to wfGetCaller( $callerOffset + 1 )

* Documented the meaning of wfGetCaller() parameter

* Added unit test

Set the status code to 500 on exceptions.

Should fix bug 37140, scripts served through
action=raw failing due to being served a html
error page.
As well as such as giving a better behavior
such as for search engines.
This could affect IE users by showing them
smart errors instead of the content, though.

The 4th Database::select() parameter is the function name.
The ORDER BY should be at $options.
This was throwing errors in PHP 5.4 due to the array being
converted to a string down at Database.php:862

Fix for Ibe3e88fa (a12ce17c): Moved WikiPage::getDeletionUpdates() near WikiPage::doDeleteUpdates().

Please group related methods instead of adding new at the bottom along with deprecated ones. Thanks.
