[TYPO3-core] RFC: Bug #11985: Optimize disposal of t3lib_PageRenderer

[Oliver Hader]

This is an SVN patch request.

Type: Bugfix / API modification

Bugtracker references:
http://bugs.typo3.org/view.php?id=11985

Branch: Trunk

Problem:
t3lib_PageRenderer is currently used in the TYPO3 backend and frontend.
There the classes template and tslib_fe inherit from t3lib_PageRenderer.
However, in frontend disposal it's not required to have the feature set
of the page renderer loaded if a request gets served by the cache and
nothing is rendered at all.

Solution:
Thus, instead of using "tslib_fe extends t3lib_PageRenderer", an
aggreation shall be used. Extension can then access the page renderer
e.g. by $TSFE->getPageRenderer()->addJsFile().
The patch increases performance of a cached page by approx. 5%.

Notes:
The initial patch was created by Steffen Kamper. Due to the downtime of
the mailing list we worked and discussed on via mail and Skype.
