3c1cfd0376 Add -msoft-float to COPTS to stop GCC attempting to be "smart" and using 
floating point registers for various optimisation tweaks.

22f14eaadf Fix a race condition in pthread_join(). All of the following must occur 
atomically:

1) Search _thread_list for the thread to join.
2) Search _dead_list for the thread to join.
3) Set the running thread as the joiner.

While we're at it, fix a race in the case where multiple threads try to
join on the same thread.  POSIX says that the behavior of multiple joiners
is undefined, but the fix is cheap as a result of the other fix.

97220dbd1e - Add trylock variants of shared and exclusive locks. 
- The sx assertions don't actually need the internal sx mutex lock, so
  don't bother doing so.
- Add a new assertion SX_ASSERT_LOCKED() that asserts that either a
  shared or exclusive lock should be held.  This assertion should be used
  instead of SX_ASSERT_SLOCKED() in almost all cases.
- Adjust some KASSERT()'s to include file and line information.
- Use the new witness_assert() function in the WITNESS case for sx slock
  asserts to verify that the current thread actually owns a slock.

e58c0d25fb - Add a new witness_assert() to perform arbitrary locking assertions. 
- Clean up the KTR tracepoints to be slighlty more consistent and useful
- Fix a bug in WITNESS where we would recurse indefinitely and blow the
  stack when acquiring Giant after sleeping with a sleepable lock held.

f4029cf62b - Always use the proc lock of the task leader to protect the peers list of 
processes.
- Don't construct fake call args and then call kill().  psignal is not
  anymore complicated and is quicker and not prone to locking problems.
  Calling psignal() avoids having to do a pfind() since we already have a
  proc pointer and also allows us to keep the task leader locked while we
  kill all the peer processes so the list is kept coherent.
- When a kthread exits, do a wakeup() on its proc pointers.  This can be
  used by kernel modules that have kthreads and want to ensure they have
  safely exited before completely the MOD_UNLOAD event.

6b7be17eed Now that we've got it, use FDOPT_NOERRLOG for fdformat and fdwrite to 
avoid blasting the syslog with error messages from bad floppies.  Both
tools have their own error reporting anyway (which could easily be
cluttered by the syslog output on your terminal).

9e705f87d9 Increase column widths when using -i (they are now wide enough to 
hold a 64bit or 32bit ~0 value, i.e. 20 and 10; this anticipates
soon-to-be machines with Exahertz rtc interrupt frequencies. :-)
