pmap: dynamically allocate the whole user page tree map
* i386/intel/pmap.c: switch to dynamic allocation of all the page tree
map levels for the user-space address range, using a separate kmem
cache for each level. This allows to extend the usable memory space
on x86_64 to use more than one L3 page for user space. The kernel
address map is left untouched for now as it needs a different
initialization.
* i386/intel/pmap.h: remove hardcoded user pages and add macro to
recontruct the page-to-virtual mapping
