The first 4 patches fix the ambiguous guest_lobase parameter,
which affects an odd usage of a bare metal image with qemu-arm.

The rest of the patches improve bsd-user to use probe_guest_base.

Changes for v2:
  - read_self_maps rewrite (warner)
  - rebase and r-b applied.

I've tested the patch for Linux-user (not bsd-user), you you may add
to the whole series:
