========================
1. Internal API changes
========================

	a. virtual_file_ex

virtual_file_ex takes now a TSRM context as last parameter:
CWD_API int virtual_file_ex(cwd_state *state, const char *path, 
 verify_path_func verify_path, int use_realpath TSRLS_DC);

	b. stat/lstat support

lstat is now available on all platforms. On unix-like platform
php_sys_lstat is an alias to lstat (when avaible). On Windows it is now 
available using php_sys_lstat. php_sys_stat and php_sys_lstat usage is recommended 
instead of calling lstat directly, to ensure portability.
