a67b22d67f Change some variables from int to size_t. This is more accurate since
these variables represent sizes in one capacity or another.  There is
no reason to allow negative numbers.  Change userspace shared structure
elements that get used for the modified functions from int to uint32_t,
since it's not clear what userspace programs use these fields, and we
do not want to break binary compatibility.  This fixes a panic when
corrupt or bogus data is passed into the kernel.

834340ae9a It seems to be safe to ignore 'file not locked' error
from server.  This effectively suppresses 'Unmapped error 1:158'.

ed9e2ed449 Although we check the return value of copyin(9) while determaining how
long the string is in userspace, afterwards we call malloc(M_WAITOK),
which could sleep for an unknown amount of time. Check the return
value of copyin(9) just to be sure that nothing has changed during that
time.

90af4afacb - Merge struct procsig with struct sigacts.
- Move struct sigacts out of the u-area and malloc() it using the
  M_SUBPROC malloc bucket.
- Add a small sigacts_*() API for managing sigacts structures: sigacts_alloc(),
  sigacts_free(), sigacts_copy(), sigacts_share(), and sigacts_shared().
- Remove the p_sigignore, p_sigacts, and p_sigcatch macros.
- Add a mutex to struct sigacts that protects all the members of the struct.
- Add sigacts locking.
- Remove Giant from nosys(), kill(), killpg(), and kern_sigaction() now
  that sigacts is locked.
- Several in-kernel functions such as psignal(), tdsignal(), trapsignal(),
  and thread_stopped() are now MP safe.

4093529dee - Move p->p_sigmask to td->td_sigmask. Signal masks will be per thread with
a follow on commit to kern_sig.c
 - signotify() now operates on a thread since unmasked pending signals are
   stored in the thread.
 - PS_NEEDSIGCHK moves to TDF_NEEDSIGCHK.

0adb6d7a49 Remove the hto(be|le)[slq] and (be|le)toh[slq] macros defined in
_KERNEL scope from "src/sys/sys/mchain.h".

Replace each occurrence of the above in _KERNEL scope with the
appropriate macro from the set of hto(be|le)(16|32|64) and
(be|le)toh(16|32|64) from "src/sys/sys/endian.h".

985cce5132 - Change mb_copy_t to take a size_t as the length argument instead of an
int.
- Change the local variable in smb_copy_iconv() from an int to a size_t.

These make smb_copy_iconv() happy in a 64-bit world.

70d4d0c0f5 Convert use of p_siglist and old SIG*() macros to use <sys/ksiginfo.h>
prototyped functions to get a sigset_t, and further to check for any
queued signals, rather than an empty signal set, to go with the move
to signal queues rather than signal sets.
