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.

f4fc9a153c ctdb-logging: Remove debug levels DEBUG_ALERT and DEBUG_CRIT
Internally map them to DEBUG_ERR to limit code churn.

This reduces the unwieldy number of debug levels used by CTDB.  ALERT
and CRIT aren't of much use as separate errors, since everything from
ERR up should always be logged.  In future just ERR can be used.

This also improves compatibility with Samba's debug.c system priority
mapping.

b4589b954e ctdb-logging: Update to use Samba style debug.h/debug.c
Samba's debug subsystem has changed a lot, so CTDB's logging needs
to be rewritten to be compatible.

The new debug.h/debug.c can't just be pulled in because it has some
extra dependencies into Samba's lib/util.  For now, to support the
smallest possible patch, implement a minimal subset of Samba's
debug.[ch] that just supports the DEBUG_CALLBACK logtype.

Define a callback for each logging method.

Check later to see if debug_extra (or similar) can somehow be
implemented using debug classes.

The timestamp on CTDB CLI tool and test program DEBUG() output goes
away, so update the unit test code to cope.

ebd9c7a277 Logging: Map TEVENT_DEBUG_FATAL to DEBUG_CRIT
This is currently mapped to DEBUG_EMERG.  CTDB really has no business
logging anything at EMERG level since the whole system is not about to
abort or catch fire.  EMERG causes the message to appear on the
console and on every terminal.  That's a bit overzealous!

There would be very few situations where logs are being filtered at
level below ERROR, so CRIT should certainly suffice.

The trigger for this was curious messages saying "No event for <n>
seconds!" logged in a user's terminal.
