[svn-r197] Changes since 19980129

----------------------

./config/freebds2.2.1
./config/irix64
./config/linux
	Added -DH5T_DEBUG to the debugging flags.  Also changed `true'
	to `:' for the Irix64 ranlib program.  This turns on printing
	of data type conversion statistics when the program exits.

./html/Datatypes.html
	Fixed documentation for data conversion functions and updated
	examples.

./src/H5D.c
	The I/O pipeline updates data type conversion statistics.

./src/H5T.c
./src/H5Tconv.c
./src/H5Tpkg.h
./src/H5Tpublic.h
	Cleaned up data type conversion registration interface.
