libaml: new io interface, add amlnew()/amltake()/amldrop(), late binding names, FindSetLeftBit/FindSetRightBit

new io interface was added. user defines amlmapio() and amlunmapio() functions
that will fill out Amlio structure with function pointers to read/write
routines for a particular region.

amlnew() function added allowing the creation of aml objects like buffers
or packages. these can be passed to amleval() with b, p or * format.

amltake()/amldrop() exclude an aml object from garbage collection.

on load, names are not always resolvable until the whole table is loaded.
for this, we create n objects that are just name strings. after load, we
recursively traverse the namespace and resolve them (see fixnames()).

the FindSetLeftBit and FindSetRightBit opcodes got implemened.
