[TYPO3-core] RFC: Link from GoogleAdWords to typo3-based site fails due wrong alias handling

> Summary: Google AdWords adds parameter to the destination URL to help 
> site owners identify visits from AdWords. URL looks like: 
> "http://berni.calis.lv/?gclid=COjNhtPk3oYCFQZWMAodOVur4w". 
> Unfortunately  setIDfromArgV() function in tslib_fe tries to use the 
> first parameter block in query string as alias. Thus if query string 
> does not start with ampersand character (which is wrong anyway!), it 
> will treat "gclid=COjNhtPk3oYCFQZWMAodOVur4w" as alias and typo3 will 
> display "not found" message.
>
> Solution: since aliases cannot contain equals sign, check for this 
> sign and do not treat parameter block as alias. Patch is tested on the 
> live site.

> Note: it seems that such urls do not fail always. They work without 
> this patch on my localhost but do not work on production server. In 
> any case I think this patch makes better detection for aliases than 
> current code. It also solves ugly "http://something/?&no_cache=1" and 
> makes possible to use correct "http://something/?no_cache=1"


Fine, an alias should not contain a '='. Did not test it.
