Retain kf_sock_inpcb field in the struct kinfo_file in <sys/user.h>. The
exp-run detected a minimal use of the field in ports:
* sysutils/lsof - patched upstream
* net-mgmt/netdata - patch accepted upstream
* emulators/qemu-user-static - upstream master branch seems not using
the field anymore
We can keep the field around for some time, but eventually it may be
reused for something else.

Remove the cloned file descriptors for /dev/crypto.

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.
