"connected". Allow "rm" or "recmaster" to be a nodespec for the
recovery master. Better error handling for interaction with ctdb
client.

nodespecs. Since we're now explicitly using bash, use local variables
when sensible.

Encode the database name in the header so we dont need to provide the database
name when doing a restore
Encode a timestamp in the header telling us when the backup was created

ctdb backupdb : which will copy a database out from ctdb and write it to a file
ctdb restoredb : which will read a database backup from a file and write it into ctdb

This file creates additional locking stress on the backend filesystem and we may not need it anyway.

address/name. To implement this stderr has redirected to stdout -
this doesn't need to be done but is the simplest implementation.
Remove -t option since it doesn't seem to accomplish much but causes
spurious messages to be displayed by ssh. Add explicit -h and --help
options. Make style of usage message consistent with documentation.
Document new features in doc/onnode.1.xml.

lvs: which shows which nodes are active LVS servers
lvsmaster: which shows which node is the lvs master multiplex node
pnn: which prints the pnn of the local node

make ctdb uptime print how long the recovery took
in the recovery daemon when we check that the public ip address
allocation on the local node is correct (we have the ips we should have
and we dont have any we shouldnt have) use ctdb uptime and check the
recovery start/stop times and make sure we dont check for ip allocation
inconsistencies during a recovery where the ip address allocation is in flux.

this callback is called for every node where the control failed (or timed out)
when we issue the start recovery control from recovery master,
set any node that fails as a culprit so it will eventually be banned

ctdb_attach() so that we can pass TDB_NOSYNC when we attach to
a persistent database and want fast unsafe writes instead of
slow but safe tdb_transaction writes.
enhance the ctdb_persistent test suite to test both safe and unsafe writes

This enhances the framework for sending tcp tickles to be able to send ipv6 tickles as well.
Since we can not use one single RAW socket to send both handcrafted ipv4 and ipv6 packets, instead of always opening TWO sockets, one ipv4 and one ipv6 we get rid of the helper ctdb_sys_open_sending_socket() and just open (and close) a raw socket of the appropriate type inside ctdb_sys_send_tcp().
We know which type of socket v4/v6 to use based on the sin_family of the destination address.
Since ctdb_sys_send_tcp() opens its own socket we no longer nede to pass a socket
descriptor as a parameter. Get rid of this redundant parameter and fixup all callers.
(This used to be ctdb commit 406a2a1e364cf71eb15e5aeec3b87c62f825da92)
This allows us to use the async framework also for controls that return
outdata.
Add a "capabilities" field to the ctdb_node structure. This field is
only initialized and kept valid inside the recovery daemon context and not
inside the main ctdb daemon.
change the GET_CAPABILITIES control to return the capabilities in outdata instead of in the res return variable.
When performing a recovery inside the recovery daemon, read the capabilities from all connected nodes and update the ctdb->nodes list of nodes.
when building the new vnnmap after the database rebuild in recovery, do not include any nodes which lack the LMASTER capability in the new vnnmap.
Unless there are no available connected node that sports the LMASTER capability in which case we let the local node (recmaster) take on the lmaster role temporarily (i.e. become a member of the vnnmap list)
(This used to be ctdb commit 0f1883c69c689b28b0c04148774840b2c4081df6)
Define two capabilities :
can be recmaster
can be lmaster
Default both capabilities to YES
Update the ctdb tool to read capabilities off a node

If no other node is hosting this public ip at the moment, then assign it immediately to the current node.
