Fix a deadlock when trying to power off a USB device. The deadlock
happens because the code in question is trying to modify the parent
USB port registers outside the USB explore thread.

The TCP delayed ACK logic isn't aware of LRO passing up large aggregated
segments thinking it received only one segment. This causes it to enable
the delay the ACK for 100ms to wait for another segment which may never
come because all the data was received already.
Doing delayed ACK for LRO segments is bogus for two reasons: a) it pushes
us further away from acking every other packet; b) it introduces additional
delay in responding to the sender. The latter is especially bad because it
is in the nature of LRO to aggregated all segments of a burst with no more
coming until an ACK is sent back.
Change the delayed ACK logic to detect LRO segments by being larger than
the MSS for this connection and issuing an immediate ACK for them to keep
the ACK clock ticking without interruption.

- Be verbose on where pkg is being bootstrapped from.
- Add support for reading configuration files from /etc/pkg.
For now only /etc/pkg/FreeBSD.conf is supported.
- Add test package signing key fingerprint into /etc/keys/pkg/trusted.
- Disable fingerprint checking by default for now as the official

Fix long-standing issue with incorrect radix mask calculation.
Usual symptoms are messages like
rn_delete: inconsistent annotation
rn_addmask: mask impossibly already in tree
routing daemon constantly deleting IPv6 default route
or inability to flush/delete particular prefix in ipfw table.
Changes:
* Assume 32 bytes as maximum radix key length
* Remove rn_init()
* Statically allocate rn_ones/rn_zeroes
* Make separate mask tree for each "normal" tree instead of system
global one
* Remove "optimization" on masks reusage and key zeroying
* Change rn_addmask() arguments to accept tree pointer (no users in base)
MFC changes:
* keep rn_init()
* create global mask tree, protected with mutex, for old rn_addmask
users (currently 0 in base)
* Add new rn_addmask_r() function (rn_addmask in head) with additional
argument to accept tree pointer

Provide a working example line for an interface with 1 address running
with CARP.
Currently, we've got a problem that interface isn't IFF_UP at the time
we assign it a redundant address, and the latter gets stuck in INIT state.
Additional SIOCSIFFLAGS from ifconfig(8) kicks it to a working state.
A proper fix is kernel side and appeared to be non-trivial, not to be
checked in before 10.0-RELEASE.

Move the resource allocation from the ata_*_probe section to the ata_*_attach
section. This prevents a boot crash on nearly all iMacs and PowerMacs/Books.
The allocation in the probe section was working before because ata_probe was

a BUS_PROBE_DEFAULT which can invoke a second DEVICE_PROBE which results in
a "failed to reserve resource" exit.
