* Description: 

* This maps Symbian OS memory management onto Icu Umemory functions

* Memory is allocated from the shaper internal heap, which has been saved in the TLS.

* If there is no memory available these memory functions leave, this is caught in the shaper wrapper.

* For debugging there is an alternative set of functions which log memory allocations
