3314a09aaf ctdb-daemon: Drop implementation of global transaction controls
These were used in serial recovery and for restoring databases using
older ctdb tool.  New code uses database specific transaction controls.

87b49c913f ctdb-daemon: Deletion of IPs is deferred until the next takeover run
This drastically simplifies the code.  "ctdb reloadips" behaves the
same, since it causes a takeover run immediately after IPs are
deleted.  "ctdb delip" now needs to be followed with an explicit "ctdb
ipreallocate".

9dc3b117e2 ctdb-takeover: Recovery daemon no longer passes fail callback
Banning is now handled by the takeover code sending banning credit
messages.

This commit makes a change in behaviour quite obvious.  Takeover runs
were initiated from several locations in the code but banning was only
done from one of these locations.  Now banning can be done from any
failed takeover run.

5b7bb6056b ctdb-ipalloc: ctdb_takeover_run_core() takes ipalloc_state
As do the functions called below it.  They no longer need a CTDB
context.

create_merged_ip_list() now takes both a CTDB context and an
ipalloc_state.

Drop ipalloc_state from CTDB context.  So the substitution in the
code is:

  ctdb->ipalloc_state  ->  ipalloc_state

Tweak the test code to match.
