Compound datatypes may not have members of size 0 (#2243)
* Compound datatypes may not have members of size 0
A member size of 0 may lead to an FPE later on as reported in
CVE-2021-46244. To avoid this, check for this as soon as the
member is decoded.
This should probably be done in H5O_dtype_decode_helper() already,
however it is not clear whether all sizes are expected to be != 0.
This fixes CVE-2021-46244 / Bug #2242.

* Rework error recovery code in H5O__dtype_decode_helper() and
H5O__dtype_decode().
* Format changes for src/H5Odtype.c.
