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.

fields of dt_module_t. Previously, this was only done on architectures where
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.
