The mobj interface is changed to use reference counting of mobjs, the
direct mobj_free() call is replaced by mobj_put(). As expected a

This also changes already present reference counting in struct
mobj_reg_shm to use the reference counting mechanism now available in

The VM_FLAG_EXCLUSIVE_MOBJ flag is removed since the referenced mobj is
put instead when a struct vm_region is removed.

As a consequence user_ta_map(), vm_map_pad() and vm_map() takes one more
argument, the flags field.

struct vm_region also gains a flags field, but since only the lower bits
are used in the flags and attr fields they are each stored as uint16_t

With this can multiple threads try to load a TA at once, the first one
taking the lock will add all the slices to the file.

The code in user_ta.c and elf_load.c using the <file.h> interface can
be optimized to allow more operations in parallel.
