Crypto file descriptors were added in the original OCF import as a way
to provide per-open data (specifically the list of symmetric
sessions). However, this gives a bit of a confusing API where one has
to open /dev/crypto and then invoke an ioctl to obtain a second file
descriptor. This also does not match the API used with /dev/crypto on
other BSDs or with Linux's /dev/crypto driver.
Character devices have gained support for per-open data via cdevpriv
since OCF was imported, so use cdevpriv to simplify the userland API
by permitting ioctls directly on /dev/crypto descriptors.
To provide backwards compatibility, CRIOGET now opens another
/dev/crypto descriptor via kern_openat() rather than dup'ing the
existing file descriptor. This preserves prior semantics in case
CRIOGET is invoked multiple times on a single file descriptor.

Add a new ioctl to disable all MSI-X interrupts for a PCI passthrough
device and invoke it if a write to the MSI-X capability registers
disables MSI-X. This avoids leaving MSI-X interrupts enabled on the
host if a guest device driver has disabled them (e.g. as part of
detaching a guest device driver).
This was found by Chelsio QA when testing that a Linux guest could
switch from MSI-X to MSI interrupts when using the cxgb4vf driver.
While here, explicitly fail requests to enable MSI on a passthrough
device if MSI-X is enabled and vice versa.

unsigned char promotes to int, which can overflow when shifted left by
24 bits or more. this has been reported multiple times but then
forgotten. it's expected to be benign UB, but can trap when built with
explicit overflow catching (ubsan or similar). fix it now.
note that promotion to uint32_t is safe and portable even outside of
the assumptions usually made in musl, since either uint32_t has rank
at least unsigned int, so that no further default promotions happen,
or int is wide enough that the shift can't overflow. this is a
desirable property to have in case someone wants to reuse the code
elsewhere.

first, the condition (mem && k < p) is redundant, because mem being
nonzero implies the needle is periodic with period exactly p, in which
case any byte that appears in the needle must appear in the last p
bytes of the needle, bounding the shift (k) by p.
second, the whole point of replacing the shift k by mem (=l-p) is to
prevent shifting by less than mem when discarding the memory on shift,
in which case linear time could not be guaranteed. but as written, the
check also replaced shifts greater than mem by mem, reducing the
benefit of the shift. there is no possible benefit to this reduction of
the shift; since mem is being cleared, the full shift is valid and
more optimal. so only replace the shift by mem when it would be less
than mem.

Specifically, if we're waking up some value n > BATCH_SIZE, then the
copyin(9) is wrong on the second iteration due to upp being the wrong type.
upp is currently a uint32_t**, so upp + pos advances it by twice as many
elements as it should (host pointer size vs. compat32 pointer size).
Fix it by just making upp a uint32_t*; it's still technically a double
pointer, but the distinction doesn't matter all that much here since we're
just doing arithmetic on it.
Add a test case that demonstrates the problem, placed with the libthr tests
since one messing with _umtx_op should be running these tests. Running under
compat32, the new test case will hang as threads after the first 128 get
missed in the wake. it's not immediately clear how to hit it in practice,
since pthread_cond_broadcast() uses a smaller (sleepq batch?) size observed
to be around ~50 -- I did not spend much time digging into it.
The uintptr_t change makes no functional difference, but i've tossed it in
since it's more accurate (semantically).

Provide a way to ask for an opaque version string for a locale_t, so
that potential changes in sort order can be detected. Similar to
ICU's ucol_getVersion() and Windows' GetNLSVersionEx(), this API is
intended to allow databases to detect when text order-based indexes
might need to be rebuilt.
The CLDR version is extracted from CLDR source data by the Makefile
under tools/tools/locale, written into the machine-generated Makefile
under shared/colldef, passed to localedef -V, and then written into
LC_COLLATE file headers. The initial version is 34.0.
tools/tools/locale was recently updated to pull down 35.0, but the
output hasn't been committed under share/colldef yet, so that will
provide the first observable change when it happens. Other versioning
schemes are possible in future, because the format is unspecified.

This sysctl value had been provided as a read-only variable that is
compiled into the C library based on the value of _PATH_LOCALBASE in
paths.h.
After this change, the value is compiled into the kernel as an empty
string, which is translated to _PATH_LOCALBASE by the C library.
This empty string can be overridden at boot time or by a privileged
user at run time and will then be returned by sysctl.
When set to an empty string, the value returned by sysctl reverts to
_PATH_LOCALBASE.
This update does not change the behavior on any system that does
not modify the default value of user.localbase.
I consider this change as experimental and would prefer if the run-time
write permission was reconsidered and the sysctl variable defined with
CLFLAG_RDTUN instead to restrict it to be set at boot time.
