Previously these were not set for the showconfig target, so took the
host's value rather than the target. As a result some machine-dependent
kernel options were not reported with correct defaults in the src.conf
manpage.

The assertions added in commit b0ccf53f24 ("inpcb: Assert against
wildcard addrs in in_pcblookup_hash_locked()") revealed that protocol
layers may pass the unspecified address to in_pcblookup().
Add some checks to filter out such packets before we attempt an inpcb
lookup:
- Disallow the use of an unspecified source address in in_pcbladdr() and
in6_pcbladdr().
- Disallow IP packets with an unspecified destination address.
- Disallow TCP packets with an unspecified source address, and add an
assertion to verify the comment claiming that the case of an
unspecified destination address is handled by the IP layer.

epairs currently shuttle all transmitted packets through a single global
taskqueue thread. To hand packets over to the taskqueue thread, each
epair maintains a pair of ring buffers and a lockless scheme for
notifying the thread of pending work. The implementation can lead to
lost wakeups, causing to-be-transmitted packets to end up stuck in the
queue.
Rather than extending the existing scheme, simply replace it with a
linked list protected by a mutex, and use the mutex to synchronize
wakeups of the taskqueue thread. This appears to give equivalent or
better throughput with >= 16 producer threads and eliminates the lost
wakeups.

sender_body() uses OPT_COPY to copy the frame into the destination slot
for the first 100,000 packets. Then it removes OPT_COPY to improve
performance. The function always starts with the first tx ring.
If multiple tx rings are in use, it is possible that the initial 100k
packets will only use the first ring. After OPT_COPY is removed, there
may come a time when the first ring is full and sender_body() will move
to the next ring which was never initialized. As a result it will send
all zero packets. (This was discovered when the receiving NIC reported
rx errors.)
Before any transmissions, step through every tx ring and set
NS_BUF_CHANGED on every slot. That will force send_packets() to
initialize the slot when first used. Since it only copies when
necessary, it performs better than always setting OPT_COPY. With this
change, there is no reason for the "drop copy" code.

When the kernel is built without capability mode support, or when
using an emulator like qemu-user-static that does not translate
system calls, these calls will return a negative number and set
the errno to ENOSYS. However, this error does not indicate a
real programming or runtime error and is generally ignored by
base system applications built with capability mode sandboxing.
Match this behavior by making xz(1) to ignore ENOSYS errors
when calling capability mode system calls too.

Split the linux_ioctl_socket() function on two counterparts, where
the linux_ioctl_socket_ifreq() intended to use in a code path which
requires the struct ifreq manipulation, i.e., translating in/out
values of the struct, while the linux_ioctl_socket() function is left
as is, it calls sys_ioctl() without touching in/out values.
Due to structures ifreq, sockaddr difference between FreeBSD and Linux
the linux_ioctl_socket_ifreq() calls kern_ioctl() directly, converting
in and out values to FreeBSD and to Linux accordingly.
Finally, modify the ifname_linux_to_bsd() to return error code, not
an unstable reference to the interface.
