  cputlb: Fix regression with TCG interpreter (bug 1310324)

Commit 0f842f8a246f2b5b51a11c13f933bf7a90ae8e96 replaced GETPC_EXT() which
was derived from GETPC() by GETRA_EXT() without fixing cputlb.c. A later
patch replaced GETRA_EXT() by GETRA() in exec/softmmu_template.h which
is included in cputlb.c.

The TCG interpreter failed because the values returned by GETRA() were no
longer explicitly set to 0. The redefinition of GETRA() introduced here
fixes this.

In addition, GETPC_ADJ which is also used in exec/softmmu_template.h is
set to 0. Both changes reduce the compiled code size for cputlb.c by more
than 100 bytes, so the normal TCG without interpreter also profits from
the reduced code size and slightly faster code.

  hw: use ld_p/st_p instead of ld_raw/st_raw

The ld_raw and st_raw definitions are only needed in code that
must compile for both user-mode and softmmu emulation.  Device
models can use the equivalent ld_p/st_p which are simple
pointer accessors.

Instead, KERNEL_IDX is renamed to KSMAP_IDX and the kernel mode accessors
wrap KSMAP_IDX and KNOSMAP_IDX.

4MB pages can use 40-bit addresses by putting the higher 8 bits in bits
20-13 of the PDE.  Bit 21 is reserved.

  target-i386: fix protection bits in the TLB for SMEP

User pages must be marked as non-executable when running under SMEP;
otherwise, fetching the page first and then calling it will fail.

With this patch, all SMEP testcases in kvm-unit-tests now pass.
