to 'fail' on error it was treated as success, because nvp!=NULL. Fix this
by not handling success under 'fail' label and by using separate variable
for parent nvpair.
If we succeeded to allocate nvlist, but failed to allocated nvpair we
would leak nvls[ii] on return. Destroy it when we cannot allocate nvpair,
before we goto fail.

'do {} while (array != NULL)' to satisfy scan-build and assert that

Now that CloudABI's sockets API has been changed to be addressless and
only connected socket instances are used (e.g., socket pairs), they have
become fairly similar to pipes. The only differences on CloudABI is that
socket pairs additionally support shutdown(), send() and recv().
To simplify the ABI, we've therefore decided to remove pipes as a
separate file descriptor type and just let pipe() return a socket pair
of type SOCK_STREAM. S_ISFIFO() and S_ISSOCK() are now defined
identically.
Now that all of the packaged software has been adjusted to either use
Flower (https://github.com/NuxiNL/flower) for making incoming/outgoing
network connections or can have connections injected, there is no longer
need to keep accept() around. It is now a lot easier to write networked
services that are address family independent, dual-stack, testable, etc.
Remove all of the bits related to accept(), but also to
getsockopt(SO_ACCEPTCONN).
With Flower (CloudABI's network connection daemon) becoming more
complete, there is no longer any need for creating any unconnected
sockets. Socket pairs in combination with file descriptor passing is all
that is necessary, as that is what is used by Flower to pass network
connections from the public internet to listening processes.
Remove all of the kernel bits that were used to implement socket(),
listen(), bindat() and connectat(). In principle, accept() and
SO_ACCEPTCONN may also be removed, but there are still some consumers
left.

The CloudABI specification has had some minor changes over the last half
year. No substantial features have been added, but some features that
are deemed unnecessary in retrospect have been removed:
- mlock()/munlock():
These calls tend to be used for two different purposes: real-time
support and handling of sensitive (cryptographic) material that
shouldn't end up in swap. The former use case is out of scope for
CloudABI. The latter may also be handled by encrypting swap.
Removing this has the advantage that we no longer need to worry about
having resource limits put in place.
- SOCK_SEQPACKET:
Support for SOCK_SEQPACKET is rather inconsistent across various
operating systems. Some operating systems supported by CloudABI (e.g.,
macOS) don't support it at all. Considering that they are rarely used,
remove support for the time being.
- getsockname(), getpeername(), etc.:
A shortcoming of the sockets API is that it doesn't allow you to
create socket(pair)s, having fake socket addresses associated with
them. This makes it harder to test applications or transparently
forward (proxy) connections to them.
With CloudABI, we're slowly moving networking connectivity into a
separate daemon called Flower. In addition to passing around socket
file descriptors, this daemon provides address information in the form
of arbitrary string labels. There is thus no longer any need for
requesting socket address information from the kernel itself.
This change also updates consumers of the generated code accordingly.
Even though system calls end up getting renumbered, this won't cause any
problems in practice. CloudABI programs always call into the kernel
through a kernel-supplied vDSO that has the numbers updated as well.

list.h includes a number of FreeBSD headers as a workaround for the
LIST_HEAD name collision. To reduce pollution, avoid including list.h
in commonly used headers when it is not explicitly needed.

It turns out that this is useful on hornet and wasp SoCs but it isn't
enabled in ye olde HAL /unless/ you were using a version from one of the
business units building USB targetted devices. It eventually got fixed
for all of them as people started wanting to use the USB ports on their
SoCs (eg for flash storage, bluetooth, 4G/LTE widgets, etc.)
This is actually a fix from ath9k but I'm merging it with the available-but-
disabled code in the QCA reference HAL.
Tested:
* AR9331 SoC
Summary:
The Ubiquiti Unifi Security Gateway is virtually identical to the
EdgeRouter Lite, with a smaller PCB and apparently a different board identifier.
Simply adding the new board identifier alongside the ERL identifier, FreeBSD
boots successfully, and can access the needed peripherals (tested with USB
booting, and basic pings on one ethernet interface)

ipfilter man pages. This also currently restricts keep frags to only when
keep state is used, which is redundant because keep state currently
assumes keep frags. This commit fixes this.
To the user this change means that to maintain the current behaviour
one must add keep frags to any ipfilter keep state rule (as documented
in the man pages).
This patch also allows the flexability to specify and use keep frags
separate from keep state, as documented in an example in ipf.conf.5,
instead of the currently broken behaviour.
Relnotes: yes
Memory is malloc'd, then a search for a match in the fragment table
is made and if the fragment matches, the wrong fragment table is
freed, causing a use after free panic. This commit fixes this.
A symptom of the problem is a kernel page fault in bcopy() called by
ipf_frag_lookup() at line 715 in ip_frag.c. Another symptom is a
kernel page fault in ipf_frag_delete() when called by ipf_frag_expire()
via ipf_slowtimer().

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same

* flesh out a "get default DFS parameters" routine
* remove the stub that returns NULL
* fix up the enable DFS method to do what FreeBSD does - specifically, allow pe_enabled
to be set/cleared.
This allows the radar pulse reporting code to function, but it doesn't yet
do anything useful.
