kernel: try to catch some (rare) mistakes

kstrcpy() did not null terminate for < 4 byte buffers. fixed,
but i dont think there is any case where this can happen in
practice.

always set malloctag in kstrdup(), cleanup.

always use ERRMAX bounded kstrcpy() to set up->errstr, q->err
and note[]->msg. paranoia.

instead of silently truncating interface name in netifinit(),
panic the kernel if interface name is too long as this case
is clearly a mistake.

panic kernel when filename is too long for addbootfile() in
devroot. this might happen if your kernel configuration is
messed up.
