NetworkManager/dispatcher/tests/test-dispatcher-envp.c
Thomas Haller 22ef6a507a build: refine the NETWORKMANAGER_COMPILATION define 
Note that:

 - we compile some source files multiple times. Most notably those
   under "shared/".

 - we include a default header "shared/nm-default.h" in every source
   file. This header is supposed to setup a common environment by defining
   and including parts that are commonly used. As we always include the
   same header, the header must behave differently depending
   one whether the compilation is for libnm-core, NetworkManager or
   libnm-glib. E.g. it must include <glib/gi18n.h> or <glib/gi18n-lib.h>
   depending on whether we compile a library or an application.

For that, the source files need the NETWORKMANAGER_COMPILATION #define
to behave accordingly.

Extend the define to be composed of flags. These flags are all named
NM_NETWORKMANAGER_COMPILATION_WITH_*, they indicate which part of the
build are available. E.g. when building libnm-core.la itself, then
WITH_LIBNM_CORE, WITH_LIBNM_CORE_INTERNAL, and WITH_LIBNM_CORE_PRIVATE
are available. When building NetworkManager, WITH_LIBNM_CORE_PRIVATE
is not available but the internal parts are still accessible. When
building nmcli, only WITH_LIBNM_CORE (the public part) is available.
This granularily controls the build.
