[svn-r19757] Purpose:
Improve h5diff performance. Description: The following changes for improving h5diff performance: 1) use HDmemcmp() before comparing each elements (memcmp() is very fast at both linew and jam) 2) replace the expensive H5Tequals() calls 3) retrieve datatype information at dataset level not each element level for compound datasets Tested: jam (linux32-LE), amani (linux64-LE), heiwa (linuxppc64-BE), tejeda (mac32-LE), linew (solaris-BE)

- Fixed h5ls to display nested compound type with curly bracket
when -S (--simple) option is used with -l (--label), so it shows
which member (in curly bracket) belong to which nested compound type
