netutils/netlib:  Add one wireless IOCTL wrapper.  For now, this is just a test to be sure that the wireless IOCTL definitions are in place.

apps/examples/usbterm:  Removed because it is not very useful and because it can be configured to use an illegal call into the OS.

apps/examples/hidkbd:  Remove call to arch_usbhost_initialize().  That is violation of the OS interfacing rules and will no longer be supported.  USB host should be initialized as part of the normal board bring-up logic as with any other devices and should not involve illegal calls from applications into the OS.
