The EIP-97 is a packet processing module found on the ESPRESSObin. This
commit adds a crypto(9) driver for the crypto and hash engine in this
device. An initial skeleton driver that could attach and submit
requests was written by loos and others at Netgate, and the driver was
finished by me.
Support for separate AAD and output buffers will be added in a separate
commit, to simplify merging to stable/12 (where those features don't
exist).

Provide MI iommu_unit, iommu_domain and iommu_ctx structs in sys/iommu.h;
use them as a first member of MD dmar_unit, dmar_domain and dmar_ctx.
Change the namespace in DMAR backend: use iommu_ prefix instead of dmar_.
Move some macroses and function prototypes to sys/iommu.h.

This is mostly an exercise to set variables to NULL/0 when declared, but
one was ensuring a string variable was set before printing it.
We should never see "<unknown>" in a printed rule; if we do then this code
definitely has some bugs that need addressing.

Note that Coverity will still treat this as an out-of-bounds access. We

going beyond that by 2B.
cmp_l2hdr was introduced in r362905.

struct _ipfw_dyn_rule is defined as packed, and as a result, its
uint64_t fields are misaligned on some 32-bit platforms. Since
pr_u64() is explicitly supposed to handle this case, avoid using a
uint64_t * for the input pointer to make sure that the compiler won't
(correctly) warn about the misalignment.

In certain situations lseek(2) will return successful although if no seek
was performed. This can happen when operating on devices that don't support
seeking (older tape drives) or when operating on changeable media devices
(such as DVD or Blu-ray devices) without a medium inserted.
Document this within the man page and update the POSIX compliance while here.

- The sequence of PB/SB entries in BAT was broken due to
off-by-one index check. It worked for smaller than

but potentially confusing. This patch fixes this.
There should be no semantics change caused by this commit.

Prior to this change a `SF_IMMUTABLE` chflagsat(2)'ed file (`path`) was left
behind, which sabotaged kyua(1) from being able to clean up the work directory,
This resulted in unnecessary work for folks having to clean up the work
directory on non-disposable systems, which defaults to `/tmp`. Use `UF_OFFLINE`
instead of `SF_IMMUTABLE`, in part because setting `SF_IMMUTABLE` isn't relevant
to the test and `SF_IMMUTABLE` cannot be cleared at all securelevels, as pointed
out by @asomers.
Additional work is required to catch cases like this upfront in the future to
avoid tester headache. See PR # 247765 for more details/followup.

r363079 introduced the possibility of loading the SCTP stack as a module in
addition to compiling it into the kernel. As part of this, the registration
of the system calls was removed and put into the loading of the module.
Therefore, the system calls are not registered anymore when compiling the
SCTP into the kernel. This patch addresses that.

Old subscription model allowed only single customer.

Differential Revision: https://reviews.freebsd.org/D25615
Subscriptions are planned to be used by modules such as route lookup engines.
In that case that's the module task to properly unsibscribe before detach.
However, the in-kernel customer - inet6 wants to track default route changes.
To avoid having inet6 store per-fib subscriptions, handle automatic
destruction internally.

It is documented as a raw hardware-based clock not subject to NTP or
incremental adjustments. With this "not as precise as CLOCK_MONOTONIC"
description in mind, map it to our CLOCK_MONOTNIC_FAST (the same
mapping as for the linux CLOCK_MONOTONIC_COARSE).
This is needed for the webcomponent of steam (chromium) and some
other steam component or game.
The linux-steam-utils port contains a LD_PRELOAD based fix for this.
There this is mapped to CLOCK_MONOTONIC.
As an untrained ear/eye (= the majority of people) is normaly not
noticing a difference of jitter in the 10-20 ms range, specially
if you don't pay attention like for example in a browser session
while watching a video stream, the mapping to CLOCK_MONOTONIC_FAST
seems more appropriate than to CLOCK_MONOTONIC.
Linux processes these clocks in reverse order and some DT relies
on this fact. For example, the frequency setting for a given PLL
is the last in the list, preceded by the frequency setting of its
following divider or so...

o unit-tests/Makefile: rework
