Martin Schwenke 9f8be709c4 debug: Avoid debug header being separated from debug text 
Currently the file backend can produce something like:

  HEADER1 HEADER2  TEXT2
    TEXT1

when different processes try to log at the same time.

Avoid this by writing the header and text at the same time using
writev().  This means that the header always has to be written by the
backend, so update all backends to do this.

The non-file backends should behave as before when they were invoked
separately to render the header.  It might be possible to optimise
some of them (e.g. via sd_journal_sendv) but this requires more
investigation (e.g. sd_journal_sendv()'s handling of newlines) and is
beyond the scope of this change.

state.header_str_no_nl takes the place of msg_no_nl for the header,
since some of the backends need the no-newline version.  It is handled
the same was as msg_no_nl: produce the no_nl version exactly once,
whether or not it is needed, since this is better than repeating it in
several backends.

README 

This directory contains libutil (until we can think of a better name)

The idea is that this library contains simple but useful data structures 
and support functions that are generally useful; not just for Samba but for 
other projects as well. Functions here should not depend on any external 
libraries, just on libc (perhaps partially provided by libreplace).
