Initial commit
Add DPMI helper functions to the DOS driver utilities to support physical->linear mapping and LDT selector management. Implemented dpmi_map_physical_to_linear (returns mapped linear address via pointer), dpmi_alloc_selector, dpmi_free_selector, dpmi_set_selector_base and dpmi_set_selector_limit using INT 0x31, returning 0 on success and -1 on error. Corresponding prototypes were added to dosutil.h to expose the new APIs for the DOS driver.
