mycroft fb526e055c Substantial signal handling changes:
* Increase the size of sigset_t to accomodate 128 signals -- adding new
  versions of sys_setprocmask(), sys_sigaction(), sys_sigpending() and
  sys_sigsuspend() to handle the changed arguments.
* Abstract the guts of sys_sigaltstack(), sys_setprocmask(), sys_sigaction(),
  sys_sigpending() and sys_sigsuspend() into separate functions, and call them
  from all the emulations rather than hard-coding everything.  (Avoids uses
  the stackgap crap for these system calls.)
* Add a new flag (p_checksig) to indicate that a process may have signals
  pending and userret() needs to do the full (slow) check.
* Eliminate SAS_ALTSTACK; it's exactly the inverse of SS_DISABLE.
* Correct emulation bugs with restoring SS_ONSTACK.
* Make the signal mask in the sigcontext always use the emulated mask format.
* Store signals internally in sigaction structures, rather than maintaining a
  bunch of little sigsets for each SA_* bit.
* Keep track of where we put the signal trampoline, rather than figuring it out
  in *_sendsig().
* Issue a warning when a non-emulated sigaction bit is observed.
* Add missing emulated signals, and a native SIGPWR (currently not used).
* Implement the `not reset when caught' semantics for relevant signals.

Note: Only code touched by the i386 port has been modified.  Other ports and
emulations need to be updated.

pk 3718fc4aa7 Allow the result of an extent allocation to be congruous to an arbitrary
number modulo the given alignment.
To do this the function extent_alloc_subregion() takes an additional `skew'
parameter.  For compatibility's sake, this function has been renamed to
extent_alloc_subregion1().

of freeing the VM resources once a process has exited.  A valid thread

thorpej 4edbfb00a8 - Add a new proclist, deadproc, which holds dead-but-not-yet-zombie
processes.
- Create a new data structure, the proclist_desc, which contains a
  pointer to a proclist, and eventually, a pointer to the lock for that
  proclist.  Declare a static array of proclist_descs, proclists[],
  consisting of allproc, deadproc, and zombproc.

thorpej 77ecf8273e Use the pool allocator and "nointr" pool page allocator for name cache entries.
The only benefit this provides is that we don't use kmem_map to map the memory
used for name cache entries (though, this is a 13 virtual page savings on my
PPro) since vnodes are never freed (they have their own freelist).

kleink 3d9b4a4320 Fix two off-by-one bugs, both present in each recvmsg(2) and sendmsg(2):
* the first one would cause an unnecessary malloc() of iovec storage for

  been allocated on the stack.
* the second one would cause a recvmsg() or sendmsg() with a msg_iovlen of
  UIO_MAXIOV to fail with EMSGSIZE, which is also a violation of XNS5.

thorpej 4b039671de When checking for overflow in the residual count, test against SSIZE_MAX.
The read/write system calls return ssize_t because -1 is used to indicate
error, therefore the transfer size MUST be limited to SSIZE_MAX, otherwise
garbage can be returned to the user.

There is NO change from existing behavior here, only a more precise
definition of that the semantics are, except in the Alpha case, where
the full SSIZE_MAX transfer size can now be realized (ssize_t is 64-bit
on the Alpha).
