Changed all K&R style functions to ANSI-style declarations within the
kernel directory. The code compiles and aparently works for i386. For
arm my toolchain does not work, but I have changed the code with great
care. Also, the make command fails for the test suite. Therefore, I
strongly recommand to review the code with care.
Edited by David van Moolenbroek to convert really all K&R functions.

Currently, the userland ABI uses a single field ('user_sp') far
into the very large 'kinfo' structure on the shared kernel
information page. This precludes us from modifying or getting
rid of 'kinfo' in the future without breaking userland. This
patch adds a separate 'kuserinfo' structure to the kernel
information page, with only information that is part of the
userland ABI, in an extensible manner. Userland now uses this
field if it is present, and falls back to the old field if not.

This change serves to reduce the clutter inside the top-level kerninfo
structure, and allows other ARM-specific values to be added on the
kernel page in one place.

Please note that this information is for use by system services only!
The clock facility is not ready to be used directly by userland, and
thus, this kernel page extension is NOT part of the userland ABI.
For service programmers' convenience, change the prototype of the
getticks(3) to return the uptime clock value directly, since the call
can no longer fail.
Correct the sys_times(2) reply message to use the right field type
for the boot time.
Restructure the kernel internals a bit so as to have all the clock
stuff closer together.
