Otherwise errors printed by the lock helper get lost.
lock_helper_args() no longer adds the program name to the list of
arguments, since vfork_with_logging() does that. Update the lock
helper to handle the extra log_fd parameter passed by
vfork_with_logging() and send stdout/stderr there.

To make this sane, also add an argv parameter and change the return
type to bool. Anticipating a subsequent change, make the type of argv
match what is needed by vfork_with_logging() and cast it when passing
to execv(). This also means changing the type of the name member of
struct db_namelist.

To avoid lock helper starvation when userspace robust mutexes are

Commit 6f072f85a1 removed reset_scheduler(),
to avoid resetting scheduler priority. However, that is not sufficient
because of commit 1be8564e55, which sets
SCHED_RESET_ON_FORK flag. With SCHED_RESET_ON_FORK, all CTDB child
processes will automatically have normal scheduling priority.

There are some potential whitespace fixes in this commit that have
