Code optimization
Description:
Eliminate many redundant lookups to check for no-op type conversion by
remembering that a type conversion path is the no-op path.
Also, don't allow non-no-op conversions which happen to be no-ops on a
particular machine (such as int<->long conversions on machines where int and
long are the same size and format, etc.) to replace the default no-op
conversion.

Bug fix.
Description:
Not all machines (like Sun and AIX) support fabsl() and fabsf() used
in test/dtypes.c. Changed the coding to use macro names HDfabsl and
HDfabsf. Also set the two macros to use ABS for now so that they will
work for all machines. (need more portable fixes which would involve
configure.)

feature
Description:
H5check_version will print warning messages if the version does not
match or if the lib version string is not consistent, even when
$HDF5_DISABLE_VERSION_CHECK is set to 1. This will mess up
tests that try to match output.
Changed it so that if $HDF5_DISABLE_VERSION_CHECK is set to 2, no
warning about version mismatch is printed.
The lib version string warning is suppressed if $HDF5_DISABLE_VERSION_CHECK
is set to any non-zero value.
