Willy Tarreau f08322b56c BUG/MINOR: trace: fix trace parser error reporting 
Since traces were adapted to support being declared in the global section
in 2.7 with commit c11f1cdf4 ("MINOR: trace: split the CLI "trace" parser
in CLI vs statement"), the method used to return the error message was
unreliable. For example an invalid sink name in the global section would
produce:

  [ALERT]    (26685) : config : parsing [test-trace.cfg:51] : 'trace': No such sink
  [ALERT]    (26685) : config : parsing [test-trace.cfg:51] : (null)
  [ALERT]    (26685) : config : Error(s) found in configuration file : test-trace.cfg
  [ALERT]    (26685) : config : Fatal errors found in configuration.

The reason is that the trace is emitted manually using ha_error() in
cfg_parse_trace() and -1 is returned without setting the message, and
the caller also prints the empty message. That's quite awkward given
that the API originally comes from the CLI which does support dynamic
strings and that config keywords do as well.

This commit modifies both cli_parse_trace() and cfg_parse_trace() to
return a dynamically allocated message instead, and adapts the central
function trace_parse_statement() to do the same, replacing a few direct
assignments with strdup() or memprintf(). This way the alert is no
longer emitted by the parser function, it just passes the message to
the caller.

A few of the static messages switching to memprintf() also took this
opportunity to report the faulty word:

  [ALERT]    (26772) : config : parsing [test-trace.cfg:51] : No such trace sink 'stduot'
  [ALERT]    (26772) : config : Error(s) found in configuration file : test-trace.cfg
  [ALERT]    (26772) : config : Fatal errors found in configuration.

This may be backported to 2.8 and 2.7.
