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

A few small changes to how pool pages are allocated/freed:
...
- If either an alloc or release function is provided, make sure both are
provided, otherwise panic, as this is a fatal error.
- If using the default allocator, default the pool pagesz to PAGE_SIZE,
since that is the granularity of the default allocator's mechanism.
- In the default allocator, use new functions:
uvm_km_alloc_poolpage()/uvm_km_free_poolpage(), or
kmem_alloc_poolpage()/kmem_free_poolpage()
rather than doing it here. These functions may use pmap hooks to
provide alternate methods of mapping pool pages.

change_owner().
* Change the semantics of chown(), fchown() and lchown(): when requesting a
change of the owner of a file, clear the set-user-id bit; analogous behaviour
for group changes.
* Since the above is a violation of the semantics specified by POSIX and
X/Open, add corresponding compatibility syscalls: __posix_chown(),
__posix_fchown(), __posix_lchown(). (Neither fchown() nor lchown() is
specified by POSIX; the prefix is intended to reflect the semantics.)
* Rename posix_rename() to __posix_rename() to follow the above convention.

Implement passing credentials as ancillary data on Unix domain sockets,

enabled with the LOCAL_CREDS socket option on the listener. Semantics are
similar to BSD/OS's:
- Creds are available with first data on SOCK_STREAM, and with every datagram
on SOCK_DGRAM.
- It is not possible to forge credentials.
Different in that:
- Different credential data structure (ours does not rely on the format
of internal kernel data structures, and does not pass the login name).
- We can pass creds and file descriptors at the same time (this does not
work in BSD/OS).
Luke Mewburn <lukem@netbsd.org> gets credit for inspiring me to implement
this. :-)

From 4.4BSD-Lite2 (noted by Frank van der Linden):
...
so_linger is used as an argument to tsleep(), so was stuffed with
clockticks for the TCP linger time. However, so_linger is set directly from
l_linger if the linger time is specified, and l_linger is seconds (although
this is not currently documented anywhere). Fix this to set the TCP
linger time in seconds, and multiply so_linger by hz when tsleep() is
called to actually perform the linger.

import chris torek's vfprintf() from libc [renamed to kprintf and all
...
floating point stuff removed].
the new kprintf replaces the 3 different (and buggy) versions of
printf that were in the kernel before (kprintf, sprintf, and db_printf),
thus reducing duplicated code by 2/3's. this fixes (or adds) several
printf formats. examples:
%#x - previously only supported by db_printf [not printf/sprintf]
%8.8s - printf would print "000chuck" for "chuck" before
%5p - printf would print "0x 1" for value 1 before
XXX: new kprintf still supports several non-standard '%' formats that
are supposed to eventually be removed:
%: - passes an additional format string and argument list recursively
%b - used to decode error registers
%r - int, but print in radix "db_radix" [DDB only]
%z - 'signed hex' [DDB only]
%n - unsigned int, but print in radix "db_radix" [DDB only]
note that DDB's "%n" conflicts with standard "%n" which takes the
number of characters written so far and stores it into the integer
indicated by the "int *" pointer arg. yuck!
while here, add comments for each function explaining what it is
supposed to do.
