[TYPO3-core] FYI24: Add feature #11707: Integrate possibility to enable/disable the deprecation logging

[Oliver Hader]

This is an SVN patch request that will be committed to SVN after 24
hours if nobody objects.

Type: Feature

Bugtracker references:
http://bugs.typo3.org/view.php?id=11707

Branch: Trunk

Problem:
In TYPO3 4.3 a deprecation logging was introduced that shall help
developers to keep track of functions/methods that have been marked as
deprecated and will be removed in a future TYPO3 release.

However, you cannot expect that all extensions will be updated in one
day and your deprecation log will keep growing. Especially on live
systems it does not make any sense to have this log file.

Solution:
Add a new setting to TYPO3_CONF_VARS that allows one to disable this
kind of logging. However, the default value is "enabled".

Notes:
Thanks to Sascha Kettler for providing a patch.
