This function Allocates a block of extended memory.

In:
   AX     = 0501h
   BX:CX  = size of block in bytes (must be non-zero)
Out:
   if successful:
     carry flag clear
     BX:CX  = linear address of allocated memory block
     SI:DI  = memory block handle (used to resize and
              free block)
