exec: introduce memory_ldst.inc.c
Templatize the address_space_* and *_phys functions, so that we can add similar functions in the next patch that work with a lightweight, cache-like version of address_space_map/unmap. Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
