Subject: [PATCH 1/5] libnm/vpn-plugin: avoid bad function pointer type casts
This makes GCC 8.0 unhappy and it is probably right about that -- it's more
difficult to get things wrong when the function prototypes actually match.

Subject: [PATCH 2/5] shared/utils/dedup-multi: make nm_dedup_multi_obj_unref()
return void
This makes its prototype compatible with GDestroyNotify so that GCC 8.0
won't warn.
The return value is not used anywhere and the unref() functions typically
don't return any.

Subject: [PATCH 4/5] all: fix -Wcast-function-type warnings
GCC 8.0's -Wcast-function-type objects casting function pointers to ones
with incompatible prototypes. Sometimes we do that on purpose though.
Notably, the g_source_set_callback()'s func argument can point to functions
of various prototypes. Also, libnm-glib/nm-remote-connection is perhaps
just not worth reworking, that would just be a waste of time.
A cast to void(*)(void) avoids the GCC warning, let's use it.
