Some cleanup to the RNDIS code:
- Minor bugfix: rndis_unit() is supposed to put the link into the
RNDIS_UNINITIALIZED state, which does not mean "unused". There's
a separate method to stop using the link. (Bug doesn't affect
anything right now because of how the code is used.)
- Reduce coupling between RNDIS code and its user(s), in preparation
for updates in that code:
* Decouple RNDIS_RESPONSE_AVAILABLE notifications from net_device
by passing just a void* handle. (Also, remove the unused return
value of the notification callback.)
* When it needs a copy of net_device stats, just ask for it
- Remove unused/untested code backing various never-used OIDs:
* RNDIS_PM, RNDIS_WAKEUP ... "should" get implemented, but the
relevant docs were unclear, ambguous, and incomplete. Someone
with access to the Hidden Gospels (maybe in the EU?) might be
able to figure out what this should do.
* RNDIS_OPTIONAL_STATS ... as the name suggests, optional. Never
implemented in part because not all the semantics were clear.
* OID_GEN_RNDIS_CONFIG_PARAMETER, which has been #if 0 forever.
- A few small whitespace fixes
Plus switch the VERBOSE symbol over to the newer VERBOSE_DEBUG style.
There should be no functional changes because of this patch; it's a
net source code shrink (because of the dead/unused code removal) and
a small object code shrink (a couple hundred bytes on ARMv5).

Some bugfixes and lots of cleanup (net code shrink):
- On reset, force the RNDIS state machine its initial state
- Hook up the RNDIS (outgoing) filters to the CDC mechanism
- Lots of cleanup:
* Eliminate duplicate copy of OID table;
* Unify handlying of the OID "query" response data pointer;
* Reduce code duplication for calculating query response lengths;
* Remove some checks for "can't happen" errors;
* Get rid of debugging #ifdefs by making the debug flag an integer level
Most of the patch, by volume, relates to those query response cleanups.
It incidentally shaves off a few hundred bytes of object code.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
