x86: page.h: move things back to their own files

Oops, asm/page.h has turned into an #ifdef hellhole.  Move
32/64-specific things back to their own headers to make it somewhat
comprehensible...

x86: page.h: move and unify types for pagetable entry definitions

This patch:

1. Defines arch-specific types for the contents of a pagetable entry.
That is, 32-bit entries for 32-bit non-PAE, and 64-bit entries for
32-bit PAE and 64-bit.  However, even though the latter two are the
same size, they're defined with different types in order to retain
compatibility with printk format strings, etc.

2. Defines arch-specific pte_t.  This is different because 32-bit PAE
defines it in two halves, whereas 32-bit PAE and 64-bit define it as a
single entry.  All the other pagetable levels can be defined in a
common way.  This also defines arch-specific pte_val/make_pte functions.

3. Define PAGETABLE_LEVELS for each architecture variation, for later use.

4. Define common pagetable entry accessors in a paravirt-compatible
way. (64-bit does not yet use paravirt-ops in any way).

5. Convert a few instances of using a *_val() as an lvalue where it is
no longer a macro.  There are still places in the 64-bit code which
use pte_val() as an lvalue.

x86: page.h: unify page copying and clearing

Move, and to some extent unify, the various page copying and clearing
functions.  The only unification here is that both architectures use
the same function for copying/clearing user and kernel pages.
