284c2b9aef Merge proc::p_mutex and proc::p_smutex into a single adaptive mutex, since 
we no longer need to guard against access from hardware interrupt handlers.

Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the
child process share the parent's lock so that signal state may be kept in
sync. Partially addresses PR kern/37437.

6d70f903e6 Network protocol interrupts can now block on locks, so merge the globals 
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:

- Inspecting process state requires thread context, so signals can no longer
  be sent from a hardware interrupt handler. Signal activity must be
  deferred to a soft interrupt or kthread.

- As the proc state locking is simplified, it's now safe to take exit()
  and wait() out from under kernel_lock.

- The system spends less time at IPL_SCHED, and there is less lock activity.

30abe39468 - Retire SYCALL_MPSAFE. With the exceptions of darwin and irix emulations, 
all system calls are now MPSAFE.

15e29e981b Merge the socket locking patch: 
- Socket layer becomes MP safe.
- Unix protocols become MP safe.
- Allows protocol processing interrupts to safely block on locks.
- Fixes a number of race conditions.

With much feedback from matt@ and plunky@.

fff5f20c25 - Give ci_want_resched a single cache line, and align. This is for monitor/ 
mwait. At least one errata sheet from Intel notes that a single line
  should be used.

a2fe0ba0a1 Fix a header decode mistake that caused mime header lines decoded by 
hfield() to be decoded as if they were "unstructured" regardless of
their type.  This resulted from calling mime_decode_hfield() with the
body of the header line, i.e., the portion after the colon header
field name terminator, rather than the full header line.
