Per XNS Issue 5, calling recvmsg(2) or sendmsg(2) with an msg.msg_iovlen less
...
than or equal to 0 shall fail with EMSGSIZE; the latter condition was not being
checked for. Also, document the msg.msg_iovlen > {IOV_MAX} case.

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
a msg_iovlen of UIO_SMALLIOV although the required amount of memory has
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.

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).

In sockargs():
...
- Add a comment describing my feelings about this interface, in general.
- Remove the COMPAT_OLDSOCK length hack. Instead, if the socket argument
is too long to fit in an mbuf, allocate enough external storage to
hold it.
- If the socket argument is a sockaddr, don't allow the length to be
greater than 255, as that would overflow sa_len.
Many thanks to enami tsugutomo <enami@cv.sony.co.jp> for his sanity checking.
