[PULL,18/33] exec/cpu: Make address_space_init/reloading_memory_map target agnostic

Commit Message

From: Philippe Mathieu-Daudé <[e-mail]>

cpu_address_space_init() and cpu_reloading_memory_map() are
target-agnostic, but are declared in "exec/exec-all.h" which
contains target-specific declarations. Any target-agnostic
source including "exec/exec-all.h" becomes target-specific and
we have to compile it N times for the N targets built.  In order
to avoid that, move the declarations to "exec/cpu-common.h" which
only contains target-agnostic declarations.
