Provides a secure way to set the block size for memory allocations.
This function sets the value of the _amblksiz global variable, which is used by malloc and other memory allocation functions to determine the smallest block of memory that might be allocated from the heap at once. If blockSize is not a multiple of two, the actual block size is the next multiple of two.
