[xdebug-general] "script" output name patch

The following patch (also attached) adds a "script" value to the
profiler_output_name option. This will write the profiler output to a
filename that consists of the script's full path (using underscores). ie:
/var/www/index.php becomes var_www_index_php_cachegrind.out.

We found it useful to associate specific file requests to profiler output.
This will only be on a per entry point basis ie: included files don't get
their own .out file. Thought it might be useful/something to consider
including.
