3BSD vfork(2), i.e. share address space w/ parent and block parent.
Keep statistics on the total number of forks, the number of forks that
block the parent, and the number of forks that share the address space
with the parent.
to be of type size_t; since this imposes an interface change on the Alpha

the previous version a compatibility system call.
whenever the %: format is used on NetBSD/Alpha. Disable %: for __alpha__.
Note: the "correct" (but untested on other architectures) fix is to
change the wrong: kprintf(cp, oflags, tp, NULL, va_arg(ap, va_list));
to the right: kprintf(cp, oflags, tp, NULL, ap);
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 *".

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.
to the stat(2) family and msync(2). This uses a primitive function
versioning scheme.
This reverts the libc shared library major version from 13 to 12, and
adds a few new interfaces to bring us to libc version 12.20.
