Add "use counting" to file entries. When closing a file, and it's reference
...
count is 0, wait for use count to drain before finishing the close.
This is necessary in order for multiple processes to safely share file
descriptor tables.

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.

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).

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>.

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.)
