The reschedule_signals() function is called when the calling thread
has the signal mask changed. For each newly blocked signal, we try to
find a thread which might have the signal not blocked. If no such
thread exists, sigtd() returns random thread, which must not be waken
up. I decided that re-checking, as suggested by PR submitter, is more
reasonable change than to change sigtd() interface, due to other uses
of sigtd(). signotify() already performs this check.

In the event the value of PATH_MAX was changed, the assumption that
MAXPATHLEN is 1024 (and hence the buffer length required to trigger
SSP to fail for read(2)) would be invalidated. Query getconf(1) for
the actual value of MAXPATHLEN via _XOPEN_PATH_MAX instead, and
increment the value by 1 to ensure that the SSP support tests the
stack smashing support properly.

When a thread enters ptracestop(), for example because it had received
SIGSTOP from ptrace(PT_ATTACH), it attempts to suspend other threads in
the same process. In the case of a thread sleeping interruptibly in an
SBDRY section, sig_suspend_threads() must wake the thread and allow it to
reach the user-mode boundary. However, sig_suspend_threads() would
erroneously avoid waking up such threads, resulting in an apparent hang.

vdev_geom.c currently uses the g_consumer's private field to point to a
vdev_t. That way, a GEOM event can cause a change to a ZFS vdev. For
example, when you remove a disk, the vdev's status will change to REMOVED.
However, vdev_geom will sometimes attach multiple vdevs to the same GEOM
consumer. If this happens, then geom events will only be propagated to one
of the vdevs.
Fix this by storing a linked list of vdevs in g_consumer's private field.
