OUString replace(sal_Unicode, sal_Unicode)

[Matteo Casalin]

Hi all,
    OUString provides the metod replace(sal_Unicode, sal_Unicode), which seems to be not widely used, while there are for sure some replaceAll("a", "b") calls here and there.
Would it be fine to rename the former to replaceAll(sal_Unicode, sal_Unicode) for consistency, fix the current calls and then slowly convert all of the call-places of the latter (which I think to be be less efficient)?
If any backward compatibility is needed, replace could be kept and just call the related replaceAll.

Thanks for any feedback
Cheers

Matteo
