Use __DECONST (instead of my own attempted re-invention) for the iov
parameters to jail_get/set(2). Similarly remove the decost-ish hack
from execvp's argv, except the __DECONST is only added at very end.
While I'm at it, remove an unused variable and fix a comment typo.
In r228193 the test of CONNPRIV have been moved to before the _usleep
and send in vsyslog(). When syslogd restarts, this would prevent the
message being logged after the disconnect/connect dance for
scenario #1.

b64_pton would sometimes erroneously fail to decode a base64 string into
a precisely sized buffer. The overflow check was a little too greedy.

Make CTL core and block backend set success status before initiating last
data move for read commands. Make CAM target and iSCSI frontends detect
such condition and send command status together with data. New I/O flag
allows to skip duplicate status sending on later fe_done() call.
For Fibre Channel this change saves one of three interrupts per read command,
increasing performance from 126K to 160K IOPS. For iSCSI this change saves
one of three PDUs per read command, increasing performance from 1M to 1.2M
IOPS.

getgroupmembership() from invoking the correct backend in the compat case.
Replace it with a nesting depth counter so it only blocks one level (the
first is the group -> group_compat translation, the second is the actual
backend). This is one of two bugs that break getgrouplist() in the compat
case, the second being that the backend's own getgroupmembership() method
is ignored. Unfortunately, that is not easily fixable without a redesign
of our nss implementation (which is also needed to implement the +@group
syntax in /etc/passwd).

Additionally fix a misparenthesization in the same check, noticed while
fixing the first bug. This bug only appears to cause problems if the same
USDT probe appears twice within a static function.

kernel modules have type ET_REL; this change fixes that. As a result, symbol
name resolution in the stack() action now works properly for kernel modules
on i386.
