===================================
Library
-------
- Fixed a bug with large external datasets
When performing a large I/O on an external dataset, the library would only
issue a single read or write system call. This could cause errors or cause
the data to be incorrect. These calls do not guarantee that they will
process the entire I/O request, and may need to be called multiple times
to complete the I/O, advancing the buffer and reducing the size by the
amount actually processed by read or write each time. Implemented this
algorithm for external datasets in both the read and write cases.
Fixes GitHub #4216
Fixes h5py GitHub #2394
- Fixed a bug in the Subfiling VFD that could cause a buffer over-read
and memory allocation failures
