Rusty Russell e120f87083 Makefile: create a library containing common, wire and bitcoin objects.
This means we don't have to manually choose what to link against,
which is much of the complexity of our Makefiles: the compiler will
automatically use any object files it needs to link.

We already do this for ccan as libccan.a, now we have libcommon.a.

We don't link against it for *everything*, as some tests require their own
versions.

Notes:
1. I get rid of the weird plugins/test/Makefile2 (accidental commit?)
2. Many tests change due to update-mocks.
3. In some places I added the missing dependency on the Makefile itself, though most are in the next
   patch.
