For scripts using dialog(1) several times, it can be visually distracting
running dpv(1) several times amidst other dialogs. The `-k' option, similar
to dialog(1) `--keep-tite', enables the same functionality to smooth ti/te.
Similar to dialog(3) keep_tite option used to prevent visually disturbing
initialization or exit that could occur when run from a script using
dpv(3) by way of dpv(1) in sequence with other dialog(1) invocations.
A new sysdecode_syscallname() function accepts a system call code and
returns a string of the corresponding name (or NULL if the code is
unknown). To support different process ABIs, the new function accepts a
value from a new sysdecode_abi enum as its first argument to select the
ABI in use. Current ABIs supported include FREEBSD (native binaries),
FREEBSD32, LINUX, LINUX32, and CLOUDABI64. Note that not all ABIs are
supported by all platforms. In general, a given ABI is only supported
if a platform can execute binaries for that ABI.
To simplify the implementation, libsysdecode's build reuses the
existing pre-generated files from the kernel source tree rather than
duplicating new copies of said files during the build.
kdump(1) and truss(1) now use these functions to map system call
identifiers to names. For kdump(1), a new 'syscallname()' function
consolidates duplicated code from ktrsyscall() and ktrsyscallret().
The Linux ABI no longer requires custom handling for ktrsyscall() and
linux_ktrsyscall() has been removed as a result.

- Start vap(s) (via ieee80211_start_all()) only when initialization
succeeds; stop the first vap otherwise (via ieee80211_stop());
- Do not try to stop a device multiple times
(move (sc->sc_flags & RTWN_RUNNING) check to urtwn_stop_locked()).

- Add some new hlist macros.
- Update existing hlist macros removing the need for a temporary
iteration variable.
- Properly define the RCU hlist macros to be SMP safe with regard
to RCU.
- Safe list macro arguments by adding a pair of parentheses.
- Prefix the _list_add() and _list_splice() functions with "linux"
to reflect they are LinuxKPI internal functions.

close or assert the bug that it is clear when leaving.
Remove an unrelated rotted comment that was attached to the buggy
clearing.
Since draining is not done in more cases, flushing is needed in more
cases, so start fixing flushing:
- do a full flush in ttydisc_close(). State what POSIX requires more
clearly. This was missing ttydevsw_pktnotify() calls to tell the
devsw layer to flush. Hardware tty drivers don't actually flush
since they don't understand this API.
- fix 2 missing wakeups in tty_flush(). Most of the wakeups here are
unnecessary for last close. But ttydisc_close() did one of the
missing ones.
This flow control bug ameliorated the design bug of requiring
potentially unbounded waits in draining. Software flow control is the
easiest way to get an unbounded wait, and a long wait is sometimes
actually useful. Users can type the xoff character on the receiver
and (if ixon is set on the sender) expect the output to be held until
the user is ready for more.
Hardware flow control can also give the unbounded wait, and this bug
didn't affect hardware flow control. Unbounded waits from hardware
flow control take a more unusual configuration. E.g., a terminal
program that controls the modem status lines, or unplugging the cable
in a configuration where this doesn't break the connection.
The design bug is still ameliorated by a newer bug in draining for
last close -- the 1 second timeout. E.g., if the user types the
xoff character and the sender reaches last close, then output is
not resumed and the wait times out after just 1 second. This is
broken, but preferable to an unbounded wait. Before this change,
the output was resumed immediately and usually completed.

This allows to do a full (non-incremental send) and receive it as a clone
of an existing dataset. It can leverage nopwrite to share blocks with the
origin. This can be used to change the relationship of datasets on the
target. For example, maybe on the source you have:
A ---- B ---- C
And you have sent to the target a full of B, and the incremental B->C:
B ---- C
You later realize that you want to have A on the target. You will have to
do a full send of A, but nopwrite can save you space on the target if you
receive it as a clone of B, assuming that A and B have some blocks inxi
common:
B ---- C
