3a56a16b06 ctdb-locking: Explicitly unlock record/db in lock helper
BUG: https://bugzilla.samba.org/show_bug.cgi?id=12469

Instead of killing lock helper processes with SIGKILL, send SIGTERM so
lock helper processes can explicitly unlock record/db.

429377a242 ctdb-ipalloc: Optimise check to see if IP is available on a node
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.

df2d6518e7 ctdb-daemon: Don't call ctdb_local_node_got_banned() on flag changes
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.
