Following connection to the local ctdbd, ctdb_cmdline_client() currently
issues a CTDB_CONTROL_GET_PNN request with a fixed 3 second timeout.
The ctdb cmd line client accepts a --timelimit argument for specifying
a per request timeout, pass this value through to ctdb_cmdline_client()
for use as a CTDB_CONTROL_GET_PNN request timeout.
(This used to be ctdb commit 0634d0305f42f17048b6830733767e8dc300e11c)
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 7f29f817fa.

ctdb_client.h is the existing internal client interface (which was mainly
in ctdb.h), and ctdb_protocol.h is the information needed for the wire
protocol only.
ctdb.h will be the new, shiny, libctdb API.

controls to register/unregister/check a server id.
a server id consists of TYPE:VNN:ID where type is specific to the
application. VNN is the node where the serverid was registered and ID
might be a node unique identifier such as a pid or similar.
Clients can register a server id for themself at the local ctdb daemon.
When a client dissappears or when the domain socket connection for the
client drops then any and all server ids registered across that domain
socket will also be automatically removed from the store.
clients can register as many server_ids as they want at the same time
but each TYPE:VNN:ID must be globally unique.
Clients have the option of explicitely unregister a server id by using
the UNREGISTER control.
Registration and unregistration can only be done by clients to the local
daemon. clients can not register their server id to a remote node.
clients can check if a server id does exist on any ctdb node in the
network by using the check control
(This used to be ctdb commit d44798feec26147c5cc05922cb2186f0ef0307be)
- fixed a valgrind error on failing to send a control
- don't mark node dead when already disconnected
- moved node list lock code into common code
(This used to be ctdb commit bcc0432d0fea7ef223f82ccee81cf35c18144b1b)
- allow a event script to be specified that will take IPs, release
IPs, and handle recovery in system specific ways
- redirect stderr in subcommands to the log
(This used to be ctdb commit de0fc9ba370db781f9c46406ed180c8211946c7a)
update the recovery test script to start all ctdb daemons with a
recovery daemon
(This used to be ctdb commit 47794e16df285cacefc30208d892d931a6e46b96)
for the time being
remove all the [de]marshalling and just pass a structure around instead
(This used to be ctdb commit b1169555ab7015976c0135ff51121cc238f5887c)
update ctdb_lmaster() return the lmaster based on this tables contents
initialize the vnn table based on number of nodes for now.
later when recovery is implemented the recovery process will populate
this mapping table.
(This used to be ctdb commit 71e440f6c26ea074f9887237c962101c8cef8c80)
CTDB_FLAG_TORTURE, which forces some race conditions to be much more
likely. For example a 20% chance of not getting the lock on the
first try in the daemon
- abstraced the ctdb_ltdb_lock_fetch_requeue() code to allow it to
work with both inter-node packets and client->daemon packets
- fixed a bug left over in ctdb_call from when the client updated the
header on a call reply
- removed CTDB_FLAG_CONNECT_WAIT flag (not needed any more)
(This used to be ctdb commit 7559dcd184666c3853127e3c8f5baef4fea327c4)
