388d18cc93 make it possible to "ctdb gettickle" to only list tickles for a certain
port.

Default is to continue to show all tickles, but if a second argument
is given, only tickles for that port will be shown.

5aa5f3e7bf Remove the structure ctdb_control_tcp_vnn since this is identical to the structure ctdb_tcp_connection.
Add a new "ctdb deltickle" command to delete tickles from the database.
This can ONLY be used for tickles created by "ctdb addtickle".

Push any "addtickle/deltickle" updates to other nodes every TickleUpdateInterval seconds'

f93440c4b7 event: Update events to latest Samba version 0.9.8
In Samba this is now called "tevent", and while we use the backwards
compatibility wrappers they don't offer EVENT_FD_AUTOCLOSE: that is now
a separate tevent_fd_set_auto_close() function.

This is based on Samba version 7f29f817fa939ef1bbb740584f09e76e2ecd5b06.

0f18859a6c Add some command-line options to ctdb_diagnostics.
In some contexts ctdb_diagnostics generates too many errors when it is
run on heterogeneous and machine-configured clusters.  In some
clusters some nodes are expected to be differently configured and also
machine-generated configured files can have comments containing
timestamps.

This adds some command-line options that can be used to reduce the
number of errors reported:

    -n <nodes>  Comma separated list of nodes to operate on
    -c          Ignore comment lines (starting with '#') in file comparisons
    -w          Ignore whitespace in file comparisons
    --no-ads    Do not use commands that assume an Active Directory Server

The -n option simply allows ctdb_diagnostics to operate on a subset of
nodes, avoiding file comparisons with and data collection on nodes
that are differently configured.  For file comparisons, instead of
showing each file on the current node and then comparing other nodes
to that file, the file from the first (available or requested) nodes
is shown and then other nodes are compared to that.  That has resulted
in changes in output - that is, ctdb diagnostics no longer prints
messages referencing the current node.

-c and -w are used to weaken comparisons between configuration files.

--no-ads can be used to avoid running ADS-specific commands if a
cluster uses LDAP (or other non-ADS) configuration.

This also fixes a number of bugs in related code:

* A call to onnode was losing the >> NODE ...  << lines because they
  now go to stderr.  This was changed in onnode long ago but
  ctdb_diagnostics was never updated to match.

* ctdb_diagnostics was counting lines in /etc/ctdb/nodes to determine
  what nodes to operate on.  For some time the nodes file has
  supported syntax that makes this invalid.  "ctdb listnodes -Y" is
  now used to list available nodes.

5699091e9a Some "ctdb ..." commands can be run without having the main daemon running.
In that case, when the main daemon is not running
the ctdb context will be initialized to NULL, since we can not connect.

Move the calls to read the ctdb socketname and connecting via libctdb to
only happen when we are executing a "ctdb ..." command that requires that we talk to the actual daemon.
Otherwise we will get an ugly SEGV for the "ctdb ..." commandline tool
when trying to run a command that is supposed to work also when the daemon is down.

protocol only.

ctdb.h will be the new, shiny, libctdb API.

6c5256ae69 In control_ipreallocate() we wait at most 5 tries before aborting the command
and returning an error.
This might not be sufficient if there are several recoveries in a row.

Instead loop as long as it takes for the recovery master to finish the recoveries and re
spond to the ipreallocate call.

Increase the log level of the error message when the recovery master was busy and could
not perform the ipreallocation promptly

4a43428440 The recent change to the recovery daemon to keep track of and
verify that all nodes agree on the most recent ip address assignments
broke "ctdb moveip ..." since that call would never trigger
a full takeover run and thus would immediately trigger an inconsistency.

Add a new message to the recovery daemon where we can tell the recovery daemon to update its assignments.

52dbd65825 onnode: update algorithm for finding nodes file.
2 changes:

* If a relative nodes file is specified via -f or $CTDB_NODES_FILE but
  this file does not exist then try looking for the file in /etc/ctdb
  (or $CTDB_BASE if set).

* If a nodes file is specified via -f or $CTDB_NODES_FILE but this
  file does not exist (even when checked as per above) then do not
  fall back to /etc/ctdb/nodes ((or $CTDB_BASE if set).  The old
  behaviour was surprising and hid errors.
