Add two new functions to the libusb20 API and required kernel ioctls.
- libusb20_dev_get_iface_desc
- libusb20_dev_get_info
New command to usbconfig, "show_ifdrv", which will print out the kernel driver
attached to the given USB device aswell.
See "man libusb20" for a detailed description.
Some minor style corrections long-line wrapping.

- specification claims that 1 second is just a maximum controller reset time;
implement controller reset properly to save almost 1 second of boot, and
about half second of resume time;
- enable channel interrupts only after channel status reset to fix duplicate
device creation on resume due to unwanted device connection event;
- as described in specification, wait for disk ready status after channel
power-up; it is not so important when disk already touched by BIOS, but
solves device not ready problems on resume and probably some other cases.
- uncomment channel stop/start on soft-reset as it is declared mandatory by
specification; it was commented due to some random drive detection problems
on VIA and JMicron controllers, but I hope it is fixed by previous point.
If the file system backing a process' cwd is removed, and procstat -f PID
is called, then these messages would have been printed. The extra verbosity is
not required in this situation.

Move channel softc initialization from ata_XXX_probe() to ata_XXX_attach().
Instead of calculating ata channel number as position in child device list,
pass it's real number directly from controller probe routine using ivars.
It is simpler and IMHO more correct.
revealed that a process' current working directory can be VBAD if the
directory is removed. This can trigger a panic when procstat -f PID is
run.

Giving a charactere device execute permissions doesn't have any use.
Right now there isn't a single device node in /dev that has it, except
the USB2 device node, so remove it.

longer do we require SCTP to be in the kernel for the
lib to be able to handle SCTP. We do this by moving
the CRC32c checksum into libkern/crc32.c and then adjusting
all routines to use the common methods. Note that this
will improve the performance of iSCSI since they were
using the old single 256 bit table lookup versus the
slicing 8 algorithm (which gives a 4x speed up in
CRC32c calculation :-D)

Add a note next to fields in network format.
The n_* types are not enough for compiler checks on endianness, and their
use often requires an otherwise unnecessary #include <netinet/in_systm.h>
The typedef in in_systm.h are still there.
the correct behaviour (sorting by distance from the current head position
in the scan direction) and bioq_insert_head() and bioq_insert_tail()
have a well defined (and useful) behaviour, especially when intermixed
with calls to bioq_disksort().
In particular:
- fix a bug in the existing bioq_disksort() that did not use the
current head position correctly;
- redefine semantics of bioq_insert_head() and bioq_insert_tail().
bioq_insert_tail() can now be used as a barrier
between previous and subsequent calls to bioq_disksort().
The code is heavily documented in the source code so please refer
to that for the details.
Much of this code comes from Fabio Checconi. Also thanks to Kirk
for feedback on the (re)definition of bioq_insert_tail().
NOTE: in the current tree there is only a handful of files which
intermix calls to bioq_disksort() with bioq_insert_head() and
bioq_insert_tail(). The ordering of the queue in these situation
was not specified (nor easy to figure out) before, so I doubt any
of that code could be affected by the specification of the API.
Also note that the current implementation is significantly simpler
than the previous one (also used in ata_sort_queue()).
It would be useful to reimplement ata_sort_queue() using
the same code used in bioq_disksort().
