devparse is now the preferred interface to use to parse device
strings or device:/path strings. It parses the passed in string,
mallocs the device's particular devdesc string and returns the

Allow device classes to define a parsing routine. Most device classes
already have these routines, but there's much duplication in their
use. Define an interface for a common routine to parse an individual
device. By convetion, files have the form "[device:]/path/to/file"
where device is optional (filled in to be the value of currdev)
and it starts with the dv_name field of the device, with the rest
of the name up to the device (typically a unit number, but disks
add partition inforation, and other devices may do artibtrary

Netlink has a confirmation/error reporting mechanism for the sent
messages. Kernel explicitly acks each messages if requested (NLM_F_ACK)
or if message processing results in an error.
Similarly, for multipart messages - typically dumps, where each message
represents a single object like an interface or a route - another
message, NLMSG_DONE is used to indicate the end of dump and the
resulting status.
As a result, successfull dump ends with both NLMSG_DONE and NLMSG_ERROR
messages.
RFC 3549 does not say anything specific about such case.
Linux adopted an optimisation which suppresses NLMSG_ERROR message
when NLMSG_DONE is already sent. Certain libraries/applications like
libnl depends on such behavior.
Suppress sending NLMSG_ERROR if NLMSG_DONE is already sent, by
setting newly-added 'suppress_ack' flag in the writer and checking
this flag when generating ack.
This change restores libnl compatibility.

Following facebook/zstd#2545, I noticed that one field in `seq_t` is
optional, and only used in combination with prefetching. (This may have
contributed to static analyzer failure to detect correct
initialization).
I then wondered if it would be possible to rewrite the code so that this
optional part is handled directly by the prefetching code rather than
delegated as an option into `ZSTD_decodeSequence()`.
This resulted into this refactoring exercise where the prefetching
responsibility is better isolated into its own function and
`ZSTD_decodeSequence()` is streamlined to contain strictly Sequence
decoding operations. Incidently, due to better code locality, it
reduces the need to send information around, leading to simplified
interface, and smaller state structures.

There is no real bug here, but we are still technically reading

The variable used for the checklist's default value needs to correspond
to the rc.conf variable as that's what's being parsed to determine them.
In the case of local_unbound it's missing the _enable suffix and thus
always defaults to off on revisit.
Fixes: 58eb9abb31 ("Add a line to the post-installation configuration dialog to enable the local_unbound service.")
There are a few issues here, some of which are hiding others. The first
is that we don't use double quotes around the command substitution so
every word in the conf file is treated as a separate argument to eval,
resulting in spaces being used in place of newlines and thus comments in
the file commenting out the rest of the file, not just to the end of
their line. In particular, we insert one comment just before the dumpdev
entry (the final one in the file) and so we never see dumpdev as set,
and thus set a default value of on for the menu.
The second issue is that, for dumpdev, it takes a value of AUTO not YES
when set, but we don't replace this with on when eval'ing, so then end
up giving AUTO to bsddialog which is interpreted the same as off (which
seems to match GPL dialog). Thus handle AUTO like YES otherwise it will
always appear as unchecked on revisit.
The final issue is that our case-insensitive YES/NO (and now AUTO)
replacements have no word boundaries around them so match the middle of
words too. As it happens this doesn't matter in practice at the moment,
but it could in future; currently the only effect is that it rewrites
moused_nondefault_enable to moused_offndefault_enable, but since this
variable is never read, only written based on moused(_enable) this is
harmless, but we should fix it in case a service comes along in future
that does get affected by it.
This installer option is currently totally useless, as it ends up
creating an ntpd_sync_on_start_enable="YES" entry in rc.conf, not an
ntpd_sync_on_start="YES" entry, as is the correct name. This can also be
noticed by revisiting the services menu, which parses the previously
written rc.conf.services file to set variables governing the default
menu entry values so that selecting OK regenerates the same file, as the
menu entry will use the correct variable name and thus think the entry
was not selected last time, defaulting back to off and losing the
setting.
Thus, add a special case in the loop for this option. The only other
entry that doesn't follow the *_enable pattern is dumpdev (even moused
does, it just also sets a second variable), but that also deviates in
terms of being explicitly set either way and using AUTO rather than YES,
hence why ntpd_sync_on_start follows a different pattern here and is
special-cased rather than introducing a whole new variable that governs
behaviour outside the loop.
Fixes: c153a35bfd ("bsdinstall: replace ntpdate by ntpd_sync_on_start")
