[!!!][TASK] Always use logging in authentication processes

There are several checks within AuthenticationService, AbstractUserAuthentication
and AbstractService which can be dropped now that the Logging API is fully
configurable.

The following options have no effect anymore:
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_userauth.php']['writeDevLog']
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_userauth.php']['writeDevLogBE']
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_userauth.php']['writeDevLogFE']
$GLOBALS['TYPO3_CONF_VARS']['SYS']['enable_DLOG']

The following public properties have no effect anymore and are removed:
* AbstractUserAuthentication->writeDevLog
* AbstractService->writeDevLog
