r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked). Use it in
preparation for a general review of all nodes.
This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.

tables. Some drivers needed some slight re-arrangement of declarations
to accommodate this. Change the USB pnp tables slightly to allow
better compatibility with the system by moving linux driver info from
start of each entry to the end. All other PNP tables in the system
have the per-device flags and such at the end of the elements rather
that at the beginning.

The mbuf length fields must be set before m_adj() is called else
m_adj() will not always adjust the mbuf and an unaligned read
exception can trigger inside the network stack. This can happen on
platforms where unaligned reads are not supported. Adjust a length
check to include the 2-byte ethernet alignment while at it.

variant of Microsoft RNDIS, i. e. their unofficial version of CDC ACM,
has been disabled in r261544 for resolving a conflict with umodem(4).
Eventually, in r275790 that problem was dealt with in the right way.
However, r275790 failed to put probing of RNDIS devices in question
back.
- Initialize the device prior to querying it, as required by the RNDIS
specification. Otherwise already determining the MAC address may fail
rightfully.
- On detach, halt the device again.
- Use UCDC_SEND_ENCAPSULATED_{COMMAND,RESPONSE}. While these macros are
resolving to the same values as UR_{CLEAR_FEATURE,GET_STATUS}, the
former set is way more appropriate in this context.
- Report unknown - rather: unimplemented - events unconditionally and
not just in debug mode. This ensures that we'll get some hint of what
is going wrong instead of the driver silently failing.
- Deal with the Microsoft ActiveSync requirement of using an input buffer
the size of the expected reply or larger - except for variably sized
replies - when querying a device.
- Fix some pointless NULL checks, style bugs etc.
This changes allow urndis(4) to communicate with a Microsoft-certified
USB RNDIS test token.
