This makes sure static analyzers don't warn for supposedly unsafe
code accessing variables as strings when they could be boolean after
having only checked against false.

* Do not bother with profiling data, which is just another
thing that can go wrong.
* Catch DB rollback errors to avoid getting stuck in
report() loops during network partitions.

'error' is currently disabled in Wikimedia production, but we still need
to log stack traces for fatals.

MWExceptionHandler::handleFatalError() is installed as a shutdown
function to inspect `error_get_last()` output and log the error via
MWExceptionHandler::logError(). The error is examined to determine if it
is a missing class error so that a descriptive log message can be
provided instructing the server administrator on 3rd party library
installation methods.

Follows-up 399ba2fecf which didn't include any translation of the error
type in the logged message (e.g. "PHP Notice" or "PHP Warning").

* Remove use of 'error' where it's redundant.
* Remove call to logException from responsibility of MWException.
Call from exception handler instead.

Previously, non-MediaWiki exceptions were logged only for api requests,
job runner, resource loader, etc. but not for general requests
such as page views.

Swapped some "$var type" to "type $var" or added missing types
before the $var. Changed some other types to match the more common
spelling. Makes beginning of some text in captial.

One of the causes (if not the cause) of bug 56269 is if something
manages to throw an exception that makes it to MediaWiki::run's
last-resort exception catcher while having an open database transaction:
the transaction never gets committed or rolled back, so it gets
implicitly rolled back and a warning is raised.
The API has the opposite problem in bug 63145: it catches the exception
but then does the normal DB shutdown which *commits* the transaction.
This is certainly the Wrong Thing to do.
Ideally, neither of these would ever happen because any code using
transactions would have its own try-catch that would catch any
exception, rollback the transaction, and then rethrow the exception. But
it happens anyway, so let's have both of these last-resort exception
handlers do the rollback, and also log the exception so the throwing
code has a better chance of being properly fixed.
