that we can always wait(2) for our children, and an ignored SIGCHLD
prevents that. Recent versions of bash can be convinced (due to a
bug most likely) to invoke us that way. Always return SIGCHLD to
SIG_DFL during init - we already prevent scripts from fiddling it.
All ash derived shells apparently have this problem (observed by
Martijn Dekker, and notified on the bash-bug list). Actual issue
diagnosed by Harald van Dijk (same list).
(MBR) partitioning has changed, but the changes have not yet been written
back to disk, we need to ignore the kernels idea of the disklabel and
instead continue with an empty one.
We need to call meta_job_output() from meta_compat_parent()
Also, the need for extra fds for meta mode only applies when
using filemon_ktrace.c.
Since we hope to see more interfaces like that, test for
USE_FILEMON_DEV being not defined.

Remove signal9 and signal10. Reimplement the idea of these test in new
trace_thread_lwpexit_masked_sigtrap, trace_thread_lwpcreate_masked_sigtrap
and trace_thread_lwpcreate_and_exit_masked_sigtrap.
This removes 2 tests directly using low-level lwp APIs.
Replace strcpy(1) with the safer snprintf(3) which guarantees NULL
