	Changed the values of the H5T_str_t type in order to make a
	distinction between C's null terminated strings and strings
	which are not null terminated.

	The string character set and padding method are saved to the
	hdf5 file instead of using defaults.

	Added conversion function from one fixed-length string type
	to another.

./test/chunk.c
	Fixed to work with new filter API
