The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch
up to that fact and revert to their recommended match of BSD-2-Clause.

accd6aa25e libjail: Handle an error from reallocarray() when trimming the buffer.
There is no API guarantee that realloc() will not fail when the buffer
is shrinking.  Handle it by simply returning the untrimmed buffer.
While this is unlikely to ever happen in practice, it seems worth
handling just to silence static analyzer warnings.

067498ed56 jail_getid(3): add special-case immediate return for jid 0
As depicted in the comment: jid 0 always exists, but the lookup will fail as
it does not appear in the kernel's alljails list being a special jail. Some
callers will expect/rely on this, and we have no reason to lie because it
does always exist.

a9cefddd40 jail_getid(3): validate jid string input
Currently, if jail_getid(3) is passed in a numeric string, it assumes that
this is a jid string and passes it back converted to an int without checking
that it's a valid/existing jid. This breaks consumers that might use
jail_getid(3) to see if it can trivially grab a jid from a name if that name
happens to be numeric but not actually the name/jid of the jail. Instead of
returning -1 for the jail not existing, it'll return the int version of the
input and the consumer will not fallback to trying other methods.

Pass the numeric input to jail_get(2) as the jid for validation, rather than
the name. This works well- the kernel enforces that jid=name if name is
numeric, so doing the safe thing and checking numeric input as a jid will
still DTRT based on the description of jail_getid.

mount helper is named "mount_fusefs" and the jail(8) parameter is named
"allow.mount.fusefs". Special case it in libjail.

0e5c6bd436 Make it easier for filesystems to count themselves as jail-enabled,
by doing most of the work in a new function prison_add_vfs in kern_jail.c
Now a jail-enabled filesystem need only mark itself with VFCF_JAIL, and
the rest is taken care of.  This includes adding a jail parameter like
allow.mount.foofs, and a sysctl like security.jail.mount_foofs_allowed.
Both of these used to be a static list of known filesystems, with
predefined permission bits.

5e53a4f90f lib: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

6fd94039ef libjail: make allocation in jailparam_all() somewhat more robust.
Unsign some variables involved in allocation as they will never be

49f903d5fc Fix some memory allocation errors:
* jail_setv will leak a parameter name if jailparam_import fails.
* jailparam_all loses the jailparam pointer on realloc error
  (a clear freshman mistake).
* If jailparam_init fails, the caller doesn't need to jailparam_free
  the buffer.  That's not really clear, so set things to NULL allowing
  jailparam_free to work without error (though it's still not required).
