Changes since 19990616
----------------------

./src/H5T.c
./src/H5Tconv.c
	All conversion functions take an extra argument called
	`stride' which is the number of bytes to advance the source
	and destination pointers after each element is converted. If
	the value is zero then the old behavior is preserved (source
	and destination values are packed). This feature was necessary
	to implement the compound datatype conversion optimizations
	and it causes a minor change to the API (application-defined
	type conversion functions take an extra size_t stride
	argument).

./src/H5Tconv.c
	An additional compound data type conversion function was added
	which is applied unless the destination type is larger than
	the source type. I'm measuring significant performance
	increases for certain operations:

	    Test Name    Struct-Conv    Noop-Conv
			 New(Old) MB/s  New(Old) MB/s
	    ----------   -------------  -------------
	    Reordering   2.062(0.3936)  54087(0.9047)
	    Subsetting   2.901(0.6581)  40192(1.1100)
	    Shrinking    1.976(0.3925)  33628(1.1500)
	    ----------   -------------  -------------

./test/dtypes.c
	Added various compound datatype conversion tests.

	Fixed return values from functions.

./src/H5T.c
	Conversion timers are updated only if H5T debugging is turned
	on a runtime (in addition to compile time). This allows the
	data type layer to be compiled with debugging support without
	having to pay a big runtime penalty if the debugging isn't
	actually used.

./src/H5A.c
./src/H5D.c
./src/H5Ofill.c
./src/H5P.c
./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tprivate.h
./src/H5Tpublic.h
	Added the stride argument to the H5T_convert() calls. The
	stride is always zero, which means that the source and
	destination data values are packed.

./configure.in
./configure			[REGENERATED]
	If API tracing is turned off then libhdf5.settings will say
	`no' instead of nothing.

./test/flush1.c
./test/flush2.c
	Added better error messages in a couple places.
