Summary0001054: Profiler files need to support filename, function name compression
Description

Currently, the system generates cachegrind files according to old format, where:
fl=/var/www/html/supportinterface/interface/shared_library/config.php
fn=require_once::/var/www/html/supportinterface/interface/shared_library/config.php

This repeats itself and noticeable especially in large profiler files of running reports, which reach even 1GB of size.

A newer compression support was added to the format:
http://valgrind.org/docs/manual/cl-format.html

xdebug should be adjusted to support this and allow halving those 1GB large files to probably less than 500MB.

Steps To Reproduce

Should be straightforward:
1) Create a project like /var/www/html/really/long/project/name/file.php
2) Create looping function to run for 10 minutes, calling another function, doing something like file_get_contents on something.
3) profiler file should linearly increase to 1GB.

After adding the new compression feature, it should be significantly smaller (and still work in kcachegrind/Qcachegrind and the likes of course!
