The recovery helper does it's own logging, so there is no need to
pass logfd.

This avoids the extra argument of logfd to ctdb_lock_helper. The log
messages from lock helper are captured by ctdbd.

- Use fprintf() before logging is initialized

Use a "bitmap" of available IPs for each IP address instead of walking
the list of available IP addresses.
For ctdb/tests/takeover/lcp2.030.sh, this improves the time taken on
my laptop from:
real 0m11.997s
user 0m11.960s
sys 0m0.000s
to
real 0m8.571s
user 0m8.544s
sys 0m0.000s
So, when assigning all 900 IP addresses the improvement is about 25%.
For the no-op case (where all IPs are already assigned to nodes), the
extra setup adds a small fraction of a second for 900 IPs.
Intermediate cases result in intermediate improvements.

This function is currently called twice each time a node is banned.
ctdb_local_node_got_banned() is already called from the banning code,
either due to a received banning control or a node banning itself.
Given that other nodes can't set a node's BANNED flag, a node can only
be banned via the above mechanisms, so drop the redundant call.

This inserts the code from ctdb_cmdline_init() function directly in
main(), so common/cmdline.[ch] can be removed.

Earlier we were relying on SCHED_RESET_ON_FORK to reset the priority of lock
helper processes. Since SCHED_RESET_ON_FORK support has been removed, the
scheduling priority of child processes created using vfork() need to be reset
explicitly in the helper processes.
