Disable "SERVER" trace

[bobbingwide]

Requirements

Control what's traced at trace startup.
Specifically, disable "SERVER" trace.

Notes

In trace_startup some of the calls to bw_lazy_trace do not check the required trace level; they are issued as BW_TRACE_ALWAYS.

Proposed solution

Short term

Test for Information level

if ( $bw_trace_level >= BW_TRACE_INFO ) { 
   bw_lazy_trace( $_SERVER, __FUNCTION__, __LINE__, __FILE__, "_SERVER" );
   bw_lazy_trace( $_REQUEST, __FUNCTION__, __LINE__, __FILE__, "_REQUEST" );
}

Longer term

Provide UI to allow control of the data displayed at start up.
Note: This could include tracing the HTTP_RAW_POST_DATA ( See bw_trace_http_raw_post_data()).

It's not going to be easy to test using PHPUnit.
It is easy to test by just using it.
I'm going to remove the logic that traces the value of trace_options['file'] value
and add logic to trace $this->trace_options and $this->trace_files_options
if tracing is VERBOSE.
