packages: Don't create empty packages
If a package plist only contains directories, but no files, do not
create the package.
This fixes an issue where setting "package=foo" in mtree causes the
"foo" package to always be created, even if nothing else installs in
that package, because the mtree entry is always added to the plist.
This most often happens:
* With architecture-specific directories, because mtree can't install
a directory conditionally based on architecture, and
* With packages that are completely empty when a particular src.conf
knob is disabled, because mtree will still create the directories.
Although it's theoretically possible that we might want to create a
package that only contains directories, there are no such packages

Makefile.inc1: Remove svn support
We don't need this, and we don't use this. It's left over from the svn
days. We stopped supporting svn as a project entirely when 12.x went
EOL. And VCS_REVSION isn't in any current ucl file or anywhere else in

mt(1)/libmt: Add LTO-10 density codes and specs.
These were obtained from IBM specs and actual tapes/drives.
Standard LTO-10 cartriges hold 30TB raw, 75TB with 2.5:1 compression.
Premium LTO-10 cartridges hold 40TB raw, 100TB with 2.5:1 compression.
LTO-10 tape drives are not backward compatible with previous generation
LTO tapes. (This is a change from older generation drives.)
Since the Premium tape is a new thing for LTO, we'll call this density
code LTO-10P vs. the standard LTO-10. The barcode identifier for LTO-10
tapes is "LA"; the barcode identifier for LTO-10P tapes is "PA".
LTO-10 cartridges contain 1035m of tape, while LTO-10 Premium
cartridges contain 1337m of tape and have slightly higher density.
(Obtained from MAM data on actual tape cartridges and the density
report, obtained via 'mt getdensity'.) LTO-10 cartridges use a
polyethylene naphthalate (PEN) film substrate. LTO-10 Premium
cartridges use an Aramid (aromatic polyamide) substrate that is thinner

usb: umass: add SCSIEJECT quirk and fix RTW8821CU_CD (USB mode switch)
Several Realtek (and lots other) USB dongles present themselves as
CDROM device first. Upon eject they do a mode switch and suddenly
are a different kind of device (sometimes even with different IDs),
e.g., a wireless dongle.
In order to avoid the CDROM stage and rather than adding the quirk
handling to more drivers, add support to umass and if enabled
automatically eject the "CDROM" to make it the real device.
Longer-term some other drivers could stop using their hand-rolled
support for this. It is unclear as-to how much we need the list of
(eject) quirks from u3g here, or if these are very specific to that
kind of devices.

LinuxKPI: 802.11: lkpi_sta_auth_to_scan() fail graciously on lsta == NULL
Usually after a firmware crash, we see reports of crashes in
lkpi_sta_auth_to_scan(). One of the last ones was in the PR
mentioned below.
These crashes are often attributed as the problem while the real
problem happened before.
At this point try avoid the NULL pointer and to fail graciously if
lvif->iv_bss (lsta) is no longer set. This way users have a chance
to possibly recover using netif restart wlan0 rather than dealing
with a panic.
See if this helps us to better track down the original problems
rather than the follow-up crash.
On a debug kernel the KASSERT should normally have caught that
condition as well but we see panics on page faults were the log

LinuxKPI: avoid -Werror=unused-value in sort() from BUILD_BUG_ON_ZERO()
The BUILD_BUG_ON_ZERO() macro returns an (int)0 if it does not fail

libpmc: Explicitly whitelist json fields
Adds all missing Intel fields and turns jevents.c into an explicit white
list mechanism so that we no longer ignore important fields that often
invalidate the counter. The json event parser must now parse every
field on each architecture that we support. This has been tested by
running tinderbox and manually running jevent against our current json
repository. As a bonus I fixed spelling errors in the AMD JSON
definitions.
