commit 7275e0ceff8e1d85aed22b69b31b5269e1ec5d03

ctdb-tests: Use a separate directory for each local daemon
Separate directory contains configuration file, PID file, public
addresses file, socket, databases and log file.

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.

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.
