before calling it for bound thread. To avoid this problem, change
thread_schedule_upcall to not put new thread on run queue, let caller
do it, so we can tweak the new thread before setting it to run.

threads in the process have already masked the signal, so job control
is delayed. But later a thread unmasking the STOP signal should enable
job control, so in issignal(), scanning all threads in process to see
if we can direct suspend some of them, not just suspend current thread.
we can deadlock because of lock order reversals. This was not
caught because Witness ignores pool mutexes right now.

least the 4.4-lite days. This is pointless, since fortune(6) performs
its own randomization. It was also problematic for binary update
systems such as ports/security/freebsd-update. This commit simply
removes the -r option to strfile so that the datfiles are constant.

- Don't require all receivers of ipis to wait for all other receivers,
only that the sender wait for all receivers. This should reduce the
amount of time spent with interrupts disabled, which may be a cause
of ipi timeouts.

mutexes are supposed to only be used as leaf mutexes, and what appear
to be separate pool mutexes could be aliased together, it is bad idea
for a thread to attempt to hold two pool mutexes at the same time.
Slightly rearrange the code in kern_open() so that FILE_UNLOCK() is
called before calling VOP_GETVOBJECT(), which will grab the v_vnlock
mutex.
Setting the LD_DUMP_REL_PRE or LD_DUMP_REL_POST environment variables
cause rtld-elf to output a table of all relocations.
This is useful for debugging.
drivers that implemnt the i2c bit banging bus interface not have to
recompile iicbb in order to add an attachment for it.
This will mean the bktr and other definitions can go back to their
respective drivers.
