When building standalone ctdb from git repo, samba_version_file correctly
includes git sha in VERSION string. When building standalone ctdb from
tarball, samba_version_file puts UNKNOWN in the VERSION string.
Use the packaged include/ctdb_version.h file to set the correct git sha.

If 2 attempts are made to start CTDB in quick succession then it is
possible for the 2nd attempt to remove a newly created PID file from
the 1st.
If the PID file existed then the PID/SID from ctdbd_is_running() will
be passed to kill_ctdbd(). If the PID file did not exist then there
is no point removing it.

While 0000 is possible from the UNIX/POSIX point of view,
these permissions create problems in an environment with
selinux enabled, which is more strict.
This aligns the perms of the read only tracking db with other
internal dbs.

Currently only Samba is built with CTDB and since CTDB headers are not
public any more, no other application can build with CTDB. So define
CTDB_SOCKET only during build.
In future CTDB will have public API and proper way of figuring out
CTDB_SOCKET.

Recovery daemon checks if it is the recovery master before performing
certain checks. During those checks it's possible that re-election can
change the recmaster. In such a case, the recovery daemon should never
do a database recovery.
This is not complete fix since the recovery master can still change
while the recovery is going on. The correct fix is to abort recovery
if the recovery master changes.

The reason for favouring more connected node is to create a larger
cluster in case of a split brain. In split brain condition, the nodes
are not communicating across partitions and each partition will run its
own election. Among all the partitions, the node which holds the recovery
lock will eventually "win". All the other nodes which won election but
could not grab recovery lock will end up banning themselves.
This also prevents the recovery master role from bouncing between nodes
during startup when the entire cluster is restarted.
