[svn-r114] Mostly changes to add new parameter to the H5Ainit_group call. The H5D, H5P
& H5T interfaces now share datatypes & dataspaces properly also.

- Ths function returns the size of the datatype in bytes as it is stored
+ This function returns the size of the datatype in bytes as it is stored
on disk or in memory, depending on the mem_flag. Setting the mem_flag to
BTRUE returns the size in memory, BFALSE returns the size on disk.
+ NOTE:
+ This function does not compute the number of bytes for a predefined
+ library type (ie. H5T_CHAR, H5T_INT) which has not been "named" by the
+ user as field or new type.
