Mostly for the embedded people that know beforehand that they don't need
MESH at all and want to save some bytes, but also helpful for the upcoming
cfg80211 transition.

v2: forget to handle mesh_wlan_get_mode()
I added dummy defines in mesh.h so that the code doesn't get sprinkled with
"#ifdef CONFIG_LIBERTAS_MESH". As wext.c gets deleted by the upcoming
cfg80211 patch anyway, I felt free to add #ifdef's there.
Dan said that he converted mesh to new-style commands. Once this patch
lands in mainline, the #ifdef in cmd.c also goes away.
