Global: use ap_version.h

This header is used by waf to contain the generated version macros,
particularly using the git hash. For waf it's better to be in a separate
header since it then can keep track of changes on it a trigger
recompilation.

For the make build system, a dummy ap_version.h file has been added in
the missing/ folder so both implementations can co-exist.
