	* autoload.cc (GetSecurityInfo): Define new autoload function.
	(RegQueryInfoKeyA): Ditto.
	* fhandler.h (fhandler_virtual::fill_filebuf): Change return type to bool.
	(fhandler_proc::fill_filebuf): Ditto.
	(fhandler_registry::fill_filebuf): Ditto.
	(fhandler_process::fill_filebuf): Ditto.
	(fhandler_registry::value_name): Add new member.
	(fhandler_registry::close): Add new method.
	(fhandler_process::p): Remove member.
	* fhandler_proc.cc (fhandler_proc::open): Add set_nohandle after calling
	superclass method. Check return value of fill_filebuf.
	(fhandler_proc::fill_filebuf): Change return type to bool. Add return
	statement.
	* fhandler_process.cc (fhandler_process::open): Add set_nohandle after
	calling superclass method. Remove references to p. Check return value of
	fill_filebuf.
	(fhandler_process::fill_filebuf): Change return type to bool. Don't use
	dereference operator on p. Add return statement.
	(fhandler_process::format_process_stat): Fix typo.
	* fhandler_registry.cc: Add static open_key declaration.
	(fhandler_registry::exists): Assume path is already normalised. Try
	opening the path as a key in its own right first, before reverting to
	enumerating subkeys and values of the parent key.
	(fhandler_registry::fstat): Add additional code to return more relevant
	information about the registry key/value.
	(fhandler_registry::readdir): Explicitly set desired access when opening
	registry key. Remove output of buf from debug_printf format string.
	(fhandler_registry::open): Use set_io_handle to store registry key handle.
	Set value_name member. Move code to read a value from the registry to
	fill_filebuf. Add call to fill_filebuf.
	(fhandler_registry::close): New method.
	(fhandler_registry::fill_filebuf): Change return type to bool. Add code
	to read a value from registry. 
	(fhandler_registry::open_key): Make function static. Use KEY_READ as
	desired access unless this is the last path component. Check the return
	value of RegOpenKeyEx for an error instead of hKey.
	* fhandler_virtual.cc (fhandler_virtual::lseek): Check the return value of
	fill_filebuf.
	(fhandler_virtual::open): Remove call to set_nohandle.
	(fhandler_virtual::fill_filebuf): Change return type to bool. Add return
	statement.
	* security.cc (get_nt_object_attribute): New function.
	(get_object_attribute): New function.
	* security.h: Only include definitions of SE_OBJECT_TYPE and INHERITY_ONLY
	if the _ACCCTRL_H macro is not defined.
	(get_object_attribute): New function declaration.
