  Fixed issue #1506: Add garbage collection statistics feature to Xdebug.

Configuration is done through INI settings:

    xdebug.gc_stats_enable=1 Enables the collection of Garbage collection stats

Or explicitly in PHP code with:

    <?php
    xdebug_start_gcstats();

The output is written to a file baed on INI settings
`xdebug.gc_stats_output_dir` and `xdebug.gc_stats_output_name` or
explicitly as filename given to `xdebug_start_gcstats($filename)`.

  Fixed issue #1507: Add functions to access Zend Engine garbage collection metrics

Number of garbage collection runs and total of collected roots metrics
exist in Zend Engine, but are not exposed to userland. These are helpful
to integrate in development to find out scripts that trigger GC.
