        * physmem.h: Move from here...  * priv.h: ...to here.  Improve
        comments.
        (extract_access): New function.
        (struct frame): Add lock field.  Change type of may_be_mapped
        field from bool to l4_word_t.
        (struct frame_entry): Add container, shared_next and shared_prevp
        fields.
        (frame_entry_free): Renamed from frame_entry_dealloc.  Update
        callers.
        (frame_entry_create): Renamed from frame_entry_new.  Update
        callers.
        (frame_entry_use): Renamed from frame_entry_use_frame.  Update
        callers.
        (frame_entry_copy): New declaration.
        (frame_entry_destroy): Renamed from frame_entry_drop.  Update
        callers.
        (frame_entry_map): New declaration.
        (frame_entry_deallocate): New declaration.
        (frame_memory_bind): Assert that FRAME->LOCK is locked.
        (frame_release): New definition.
        (container_attach): Renamed from frame_entry_attach.  Update
        callers.
        (frame_entry_detach): Renamed from frame_entry_detach.  Update
        callers.
        * frame.c: Don't include "physmem.h".  Include "priv.h" and
        <pthread.h>.
        (frame_dump): New function.
        (frame_constructor): Initialize FRAME->LOCK and lock it.
        (frame_space): It is a space of frame structures, no frame_entry
        structures.  Fix typo.
        (frame_alloc): Initialize FRAME_MAY_BE_MAPPED.  Assert FRAME->LOCK
        is locked.
        (frame_deref): When unmapping a frame, assert that FRAME->MEMORY
        points to memory.  Unlock FRAME->LOCK on return.  Add sanity
        checks.
        (frame_add_user): Assert that FRAME->LOCK is locked.
        (frame_drop_user): Assert that FRAME->LOCK is locked.  Don't drop
        a reference.
        * frame-entry.c: Include <string.h> and "zalloc.h".
        (frame_entry_constructor): New function.
        (frame_entry_space): Use it.
        (frame_entry_dump): Don't mark as static.  Improve output.  Add
        some sanity checks.
        (frame_entry_alloc): Assert that FRAME_ENTRY->SHARED_NEXT and
        FRAME_ENTRY->SHARED_PREVP are correct.
        (frame_entry_free): Add sanity checks.
        [!NDEBUG]: Clear memory.
        (frame_entry_share_with): New function.
        (frame_entry_create): Assert CONT->LOCK is held.  Initialize
        FRAME_ENTRY->CONTAINER.  Initialize share list.
        (frame_entry_copy): New function.
        (frame_entry_use): Assert CONT->LOCK and SOURCE->LOCK are held.
        Set FRAME_ENTRY->CONTAINER.  Initialize share list.
        (frame_entry_destroy): If CONT is NULL, don't try to detach
        FRAME_ENTRY from a container.  Assert CONT->LOCK in CONT is
        non-NULL and SOURCE->LOCK are held.  Correctly update COW count.
        Only unlock FRAME_ENTRY->LOCK if DO_UNLOCK is true.
        (frame_entry_attach): Moved to container.c and renamed to
        container_attach.
        (frame_entry_detach): Moved to container.c and renamed to
        container_detach.
        (frame_entry_map): New function.
        (frame_entry_deallocate): New function.
        * container.c: Include <string.h> and "priv.h".
        (container_dump): New function.
        (container_attach): Moved from frame-entry.c and renamed from
        frame_entry_attach.
        (container_detach): Moved from frame-entry.c and renamed from
        frame_entry_detach.
        (container_allocate): Lock CONT->LOCK.  Don't check the return
        value of FRAME_ENTRY_ALLOC for errors: it is guaranteed to
        succeed.  Unlock FE->FRAME->LOCK and CONT->LOCK.
        (container_deallocate): Lock CONT->LOCK.  Refactor iteration.
        Rewrite body to use frame_entry_deallocate.  Return the number of
        bytes allocated.
        (container_map): Refactor iteration.  Rewrite body to use
        frame_entry_map.
        (container_copy): If HURD_PM_CONT_ALL_OR_NONE is set try better to
        make sure the operation won't fail mid-flight.  Lock
        SFE->FRAME->LOCK.  If the copy is a copy on write and the frame
        has extant write mappings, remove them.
        (container_ops): Moved to physmem.h.  Preface names with hurd_pm_
        to reflect presence in the global name space.
        (container_demuxer): If the invoke method produces returns an
        error code, emit a debugging message.
        (container_alloc) [!NDEBUG]: Lock CONT->LOCK.
        Unlock FE->FRAME->LOCK.
        (container_init): New function.
        (container_reinit): Assert CONT->LOCK is held.
        (container_class_init): Use CONTAINER_INIT.
        
        * physmem.h: New file.
        * headers.m4: New file.
        * physmem.c: Don't include "physmem.h".  Include "priv.h".
        * ia32-cmain.c: Likewise.
