This is a first patchset in removing target_ulong from non-target/
directories.  As use of target_ulong is spread accross the codebase we
are attempting to target as few maintainers as possible with each
patchset in order to ease reviewing.

The following instances of target_ulong remain in accel/ and tcg/
    - atomic helpers (atomic_common.c.inc), cpu_atomic_*()
      (atomic_template.h,) and cpu_[st|ld]*()
      (cputlb.c/ldst_common.c.inc) are only used in target/ and can
      be pulled out into a separate target-specific file;

    - walk_memory_regions() is used in user-exec.c and
      linux-user/elfload.c;

    - kvm_find_sw_breakpoint() in kvm-all.c used in target/;

Changes in v2:
    - addr argument in tb_invalidate_phys_addr() changed from vaddr
      to hwaddr;

    - Removed previous patch:

        "[PATCH 4/8] accel/tcg: Replace target_ulong with vaddr in helper_unaligned_*()"

      as these functions are removed by Richard's patches;

    - First patch:

        "[PATCH 1/8] accel: Replace `target_ulong` with `vaddr` in TB/TLB"

      has been split into patches 1-7 to ease reviewing;

    - Pulled in target/ changes to cpu_get_tb_cpu_state() into this
      patchset.  This was done to avoid pointer casts to target_ulong *
      which would break for 32-bit targets on a 64-bit BE host;

      Note the small target/ changes are collected in a single
      patch to not break bisection.  If it's still desirable to split
      based on maintainer, let me know;

    - `last` argument of pageflags_[find|next] changed from target_long
       to vaddr.  This change was left out of the last patchset due to
       triggering a "Bad ram pointer" error (softmmu/physmem.c:2273)
       when running make check for a i386-softmmu target.

       I was not able to recreate this on master or post rebase on
       Richard's tcg-once branch.

Changes in v3:
    - Rebased on master

Finally, the grand goal is to allow for heterogeneous QEMU binaries
consisting of multiple frontends.
