- reorder entries in src/Makefile.am so that general names
  are all at the beginning (AM_CPPFLAGS, sbin_PROGRAMS)
  and the names for a certain library/binary are grouped
  together
- have libNetworkManager.la reuse libNetworkManagerBase.la.
- let all components in src/Makefile.am use the same AM_CPPFLAGS,
  except libsystem-nm.la.
- move callouts/nm-dispatcher-api.h to shared/ directory. It
  is obviously not internal API to callouts, and callouts is
  not a library. Thus, the right place is shared/.
