                * map.h: New file.
                * map.c: New file.
                * Makefile.am (libhurd_mm_a_SOURCES): Add map.h and map.c.
                * headers.m4: Link map.h to sysroot/include/hurd/map.h.
                * pager.h: Rewrite.
                * pager.c: Likewise.
                * anonymous.h (ANONYMOUS_STAGING_AREA): New define.
                (anonymous_pager_fill_t): Don't pass the base of the region.  
Pass
                the location of the storage corresponding to the pages on which
                the faults were raised and the offset into the region.  Update
                users.
                (struct anonymous_pager): Add fields map_area, map_area_count 
and
                lock.  Remove field alloced_region.
                (anonymous_pager_alloc): Replace size parameter with length
                parameter.  Take access parameter indicating the desired access.
                Update users.
                * anonymous.c (offset_compare): Compare the values, not the
                pointers.
                (fault): Update signature to be consistent with new API.  Lock
                ANON->LOCK.  Always look up the storage descriptor corresponding
                to the faulted page.  Copy the storage to the faulted address as
                required.  Update how we call ANON->FILL to be consistent with 
the
                new API.
                (destroy): Free ANON->STAGING_AREA.
                (anonymous_pager_alloc): Update signature to be consistent with
                new API.  Allocate the staging area if ANONYMOUS_STAGING_AREA is
                set.  Allocate it separately from the main map.  Create a map
                corresponding to the region.
                (anonymous_pager_destroy): Just lock ANON->LOCK.  Don't call
                destroy, call pager_deinit.
                * mmap.c: Include <hurd/map.h>.
                (mmap): Add support for protection other than read/write.
                (munmap): Rewrite to use new API.  Use map_split to support
                splitting of memory maps.
                * exceptions.c: Don't include "pager.h", include "map.h".
                (exception_handler_normal): Don't call pager_fault but 
map_fault.
                (exception_handler_activated): Likewise.

                * ruth.c (main): Improve mmap test.  Update use of
                anonymous_pager_alloc to be consistent with new API.  Update 
fill
                functions to be consistent with new API.  Remove redundant test.

                functions to be consistent with new API.
