Return: CF clear if successful
CF set on error
AX = error code (06h,08h) (see AH=59h)
Desc:   adjust the size of the per-process open file table, thus raising or
lowering the limit on the number of files the caller can open
simultaneously
Notes:  any currently-open files are copied to the new table
if the table is increased beyond the default 20 handles, only the
first 20 will be inherited by child processes
