Relaxed behavior of H5Pset_page_buffer_size() when opening files (#4280)
This API call sets the size of a file's page buffer cache. This call
was extremely strict about matching its parameters to the file strategy
and page size used to create the file, requiring a separate open of the
file to obtain these parameters.

These requirements have been relaxed when using the fapl to open
a previously-created file:

* When opening a file that does not use the H5F_FSPACE_STRATEGY_PAGE
  strategy, the setting is ignored and the file will be opened, but
  without a page buffer cache. This was previously an error.

* When opening a file that has a page size larger than the desired
  page buffer cache size, the page buffer cache size will be increased
  to the file's page size. This was previously an error.

The behavior when creating a file using H5Pset_page_buffer_size() is
unchanged.
