Description: During last change, part of the code wasn't updated in
copy and paste accordingly. It was in the exception handling of NaN
in H5T_conv_f_f().
Solution: Corrected.
Platforms tested: No test needed - trivial.

Purpose:
Added C++ wrapper for Packet Table API.
Description:
Added macro for high-level C++ library (LIBH5CPP_HL), which changes every
Makefile.in.
Added directories for high-level C++ library (though currently only Packet
Table API is supported).
Added both C++ source and tests.

Description: The 6th step of changing conversion test. This checkin is
only for conversion of special values from floating-points to integers.
Solution: This test is seperated from regular value conversion. It reuses
the same function test_conv_int_float() in test/dtypes.c. The source buffer
of floating-point type is filled up with 8 special values, +/-0, +/-infinity,
+/-QNaN, +/-SNaN.
Also added 3 new conversion exception values H5T_CONV_EXCEPT_PINF, H5T_CONV_EXCEPT_NINF,
H5T_CONV_EXCEPT_NAN, for floating-point special values positive infinity, negative
infinity, and NaN. These values are for conversion exception callback function defined
through H5Pset_type_conv_cb(). (Remember to update the document!)

Description: The 5th step of changing conversion test. This checkin is only for conversion
of special values between floating-point types.
Solution: This test is seperated from regular value conversion. It reuse the same function
test_conv_flt_1() in test/dtypes.c. The source buffer of floating-point type is filled up
with 8 special values, +/-0, +/-infinity, +/-QNaN, +/-SNaN.

New feature & bug fix.
Description:
The scaleoffset filter was not completed at last check-in and had quite
a few bugs.
Solution:
The scaleoffset filter is now complete for compressing integers. All previous
bugs have been fixed. The filter does not compress floating-point at present.
The filter only supports integer and floating-point datatypes.

Description: The recent change of conversion between floating-point and floating-point types in dtypes.c have
detected some bugs in H5T_conv_f_f in H5Tconv.c.
Solution: This checkin is to fix these bugs. They happened in a few places in H5T_conv_f_f causing incorrect
rounding, denormalization, etc.

Optimization
Description:

datatypes, arrays, etc.) if the destination datatype is a proper superset of
the source datatype.

Bug fix
Description:
Opening an object in a group that is located in a file which has been
unmounted would cause a core dump. :-(
Solution:

names for the newly opened object in a safer way.

Purpose:
Bug fix
Description:

Configure feature
Description:
On some platforms with some compilers, automake's dependency tracking
is silently disabled. This can be confusing for developers.
Solution:
Set configure to enable dependencies all the time unless the user
explicitly disables them (using the configure flag
--disable-dependency-tracking) or a site file overrides the default
(as is the case on IRIX).

New feature
Description:
Add new "block tracker" data structure to library, for tracking blocks of
bytes in a file. Block trackers will be used to keep track of the blocks
belonging to the soon-to-be-implemented "segmented heap" which is designed to
replace the current local & global heaps (starting with the local heap).
Block trackers will also keep track of the free space in the segmented heap
and someday could be used to track the free space in the entire HDF5 file.
They are implemented as a small header of information to cache the state
of the blocks (max & min sizes of blocks tracked, etc.) and the records of
the blocks themselves are stored in a v2 B-tree.

Automake version upgrade
Description:
Upgraded automake version from 1.6.2 to 1.9.5.
Changed bin/reconfigure script to use automake 1.9.5.
Changed configure.in and Makefiles to use new FCFLAGS and FC variables
instead of FFLAGS and F9X.
Automake and configure should now do the lion's share of the work
supporting Fortran 9X; macros in acsite.m4 are now mostly unused (will
be cleaned later).
Altered how configure handles pmake; now root-level Makefile.in is
processed by bin/reconfigure to have a .MAKEFLAGS target, since
automake no longer allows us to define unused variables.
Configure now always checks for C++ compiler even if it is not
used, since automake thinks this is the Right Thing To Do and
will break otherwise.
