DOS Fn 5800H: Query Memory Allocation Strategy

                                                         Compatibility: 3.0+ 
 Expects: AX    5800H
 Returns: AX    allocation strategy code. See fn 5801H (set alloc strategy)
          CF    always clear (CF=NC=0)
    Info: Obtains a code indicating the method DOS will use in satisfying
          subsequent memory allocations (via fn 48H).

          Programs which change the allocation strategy should use this
          function and save the current setting and be sure to change it
          back (via fn 5801H) before terminating.

          See Accessing Upper Memory for info on allocating from UMBs.
