Enable joining of IBSS (AdHoc) networks

Enable joining of IBSS (AdHoc) networks

Set wpa_supplicant parameters for IBSS networks, namely
setting both mode and frequency (since wpa_supplicant
doesn't use scan results to determine which frequency
to do the IBSS on).

BUG=chromium-os:12042
TEST=Manual -- join manually created IBSS.  Also tested with new IBSS test in MatFunc: (issue 6603026)

I take it this gets us a connection via dbus?  Or can we also now select a
network via the UI?

Please use issue 12042 (and take ownership).

I prefer "hostap" to "ap" (if you change please also change the #define)

do you need to avoid sending "mode"? (i.e. just drop the if)

PTAL.  Added autotest as well.
