This adds a parameter called keep_map_locked to vm_map_lookup()
that allows the function to return with the map locked.
This is to prepare for fixing a bug with gsync where the map
is locked twice by mistake.

As described in XXX comments, the workaround for memory mapping is
implemented for 80386 and it is unnecessary on i486 or later. Thus, it
is safe to omit that if the kernel is built for the recent (1989~)
processors.
Fuhito Inagawa pointed out the problem to me.
* i386/i386/trap.c (kernel_trap): Disable the workaround when the kernel
is built for i[456]86.
* i386/intel/pmap.c (pmap_protect, pmap_enter): Ditto.
* i386/intel/read_fault.c: Define intel_read_fault if and only if it is
necessary.

Import the macro definitions from the x15 kernel project, and replace
all similar definitions littered all over the place with it.
Importing this file will make importing code from the x15 kernel
easier. We are already using the red-black tree implementation and
the slab allocator from it, and we will import even more code in the
near future.
