3df39aa7fb ctdb-scripts: Avoid ShellCheck warning SC2164
SC2164 (warning): Use 'cd ... || exit' or 'cd ... || return' in case cd fails.

A problem can only occur if /etc/ctdb/ or an important subdirectory is
removed, which means the script itself would not be found.  Use && to
silence ShellCheck.

794f125802 ctdb-tool: Add UNKNOWN pseudo state
When a node is starting, CTDB reports remote nodes as unhealthy by
default.  This can be misleading.

To hide this, report an "UNKNOWN" pseudo state when a remote node is
not disconnected and the runstate is less than or equal to
"FIRST_RECOVERY".

e752f841e6 ctdb-daemon: Use DEBUG() macro for child logging
Directly using dbgtext() with file logging results in a log entry with
no header, which is wrong.  This is a regression, introduced in commit
10d15c9e5d.  Prior to this, CTDB's
callback for file logging would always add a header.

Use DEBUG() instead dbgtext().  Note that DEBUG() effectively compares
the passed script_log_level with DEBUGLEVEL, so an explicit check is
no longer necessary.
