[TYPO3-core] RFC: #10313: Fileadmin-module wrongly allows creation of trailing dot directories on UTF8 FS

[Francois Suter]

Hi,

> Problem: 
> TYPO3 doesn't allow using directory names ending with one or more dots.
> This is ensured by function t3lib_basicFileFunctions::cleanFileName().
> 
> Unfortunately a later added check for UTF-8 file systems (aka $GLOBALS['TYPO3_CONF_VARS']['BE']['forceCharset'] == 'utf-8' && $GLOBALS['TYPO3_CONF_VARS']['SYS']['UTF8filesystem']) enables user to create and rename those directories (but not delete, upload etc.).
> 
> The attached patch prevents creating such directories or renaming a directory to a new name with trailing dots by removing them (move preg_replace to top of cleanFileName()).
> 
> Furthermore PHPDoc description was updated (Thanks to Marcus Krause)

Committed to trunk (revision 5070)
Committed to 4.2 (revision 5071)
Committed to 4.1 (revision 5072)

Actually the 4.2 patch didn't apply cleanly to 4.1. Attached is the 
adapted patch committed to 4.1.
