f1b6bdb619 ctdb-client: Fix implementation of transaction commit
There is no need to explicitly check that recovery is not active before
sending TRANS33_COMMIT control.  Just try TRANS3_COMMIT control and if
recovery occurs before the control is completed, the control will fail
and it can be retried.

Make sure g_lock lock is released after the transaction is complete.
Also, add timeout to the client api.

f721035d43 ctdb-client: Fix implementation of transaction start
Since g_lock checks if the process exists in case of conflicting lock,
there is no need to register srvid.

Transaction start returns a transaction handle and transaction
commit/cancel will free that handle.  Since we cannot call async code
in a talloc destructor, this avoids the use of talloc destructor for
cancelling the transaction.

If user frees the transaction handle instead of calling transaction
cancel, it will leave stale g_lock lock.  This stale g_lock lock  will
get cleaned up on next transaction attempt.

86f7c4d7f3 ctdb-ipalloc: Fix buggy short-circuit when no IPs are available
At the moment IP is short-circuited when there are no available IP
addresses.  However, if some IP addresses are already allocated then
"no available IP addresses" means that all the addresses should
(probably) be released.  The current short-circuit means that no
already hosted IP addresses will be released.

The short-circuit exists to avoid lots of messages saying that all IP
addresses can not be assigned at startup time.  So, add a check to
ipalloc_can_host_ips() so that it succeeds if IP addresses are already
allocated to nodes.
