Code patch for Registerfile ccp and h

RegisterFile constructor currently throws #error when both MMAP and
VIRTUALALLOC conditions fail.
On any platform that does not provide these features (for instance, Symbian),
the fallback should be regular malloc (or fastMalloc).
Memory allocation with fastMalloc functionally equivalent in this case, even
though it may have certain drawbacks such as lack of dynamic pre-allocation.

This should be the general, preferred way of fixing the issue, as opposed to
introducing conditional code block for platform Symbian.
