kern/80362: [PATCH] add preadv() and pwritev() system calls

[Marc Olzheim]

Updated the patches again:

http://www.stack.nl/~marcolz/FreeBSD/preadv.current.20050627.patch.txt

After patching, type 'make syscalls.c' in /usr/src/sys/kern and
'make sysent' in /usr/src/sys/compat/freebsd32/

Could someone please take a look at it / commit it ?
Or do you want me to put the files generated by the two 'make's into the
patch as well ?
I figured it would be better not to, since they are generated anyway...
