1. Increased the timeout on sapi/fpm tests to match the cli server
2. Disabled session GC in session_set_save_handler_basic.phpt
3. Fixed GC in save_handler.inc to delete files based on age
These were caused by the tests assuming default values for some session
configuration settings, in particular session.save_path and session.name.
The tests now explicitly set these settings in the --INI-- section.
These hopefully test a reasonable set of basic, error and variations for
the twenty or so session functions. Note however that they do not
test all the session configuration settings, nor do they test anything
with register_globals enabled.
