hdf5-1.10.0

[Takeshi Enomoto]

Hi,

The version 1.10.0 is a major update to hdf5.
Most notably, there are changes in API and hid_t is changed from
32-bit to 64-bit.

<https://www.hdfgroup.org/HDF5/doc/RM/APICompatMacros.html>

-DH5_USE_16_API, -DH5_USE_18_API may be used in ${configure.cflags}
for backward compatibility.

ncarg required the latter option (r147504).

hdfeos5 fails because int and hid_t are used interchangeably.
I created a patches  and committed in r147503.
