Modified files:

lib/libc/include libc_private.h
lib/libc/sys ftruncate.c lseek.c mmap.c pread.c
pwrite.c truncate.c
Added files:
lib/libc/gen __getosreldate.c
Log:
Change the C wrappers for mmap/lseek/pread/pwrite/truncate/ftruncate to
call the pad-less versions of the corresponding syscalls if the running
kernel supports it. Check kern.osreldate once per program and cache the
result to select the appropriate syscall. This maintains userland
compatability with kernel.old's from quite a while back.
