275d1554aa Abolition of bcopy, ovbcopy, bcmp, and bzero, phase one. 
bcopy(x, y, z) ->  memcpy(y, x, z)
ovbcopy(x, y, z) -> memmove(y, x, z)
   bcmp(x, y, z) ->  memcmp(x, y, z)
  bzero(x, y)    ->  memset(x, 0, y)

17de9df6c1 Reject an iovcnt argument of 0 to readv(), writev(), preadv() and pwritev() 
as invalid.  This has been stated by the respective manual pages at least
since Net/2, and is the behaviour specified by XSH5.

939279f988 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).

b6781dbaa2 Split up read/readv/write/writev into the system call front-end and 
the guts that actually perform the I/O request.

a4a34ba74a Add two additional arguments to the fileops read and write calls, a 
pointer to the offset to use, and a flags word.  Define a flag that
specifies whether or not to update the offset passed by reference.

97d2a58201 Fix slight argument bogosity with getgroups(), setgroups(), select(), 
and swapctl().  For the former three, they use an 'int' in their user-land
prototype which was a 'u_int' in the kernel, which screwed up automatic
generation/checking of lint syscall stubs.  For the latter, the user-land
prototype uses a "const char *", but the syscall just used "char *".

From Chris Demetriou <cgd@pa.dec.com>.

e7af2a8237 * catch up with system call argument type fixups/const poisoning. 
* Fix arguments to various copyin()/copyout() invocations, to avoid
  gratuitous casts.
* Some KNF formatting fixes

f41d0a3d9b in select(), if it's a small number of file descriptors use a 
automatic array rather than an array allocated with alloca().
(This was the only use of alloca() in the kernel, and it wasn't
necessary or consistent with the way other functions in this file
work.)
