[svn-r26329] Merge of r26069, r26070, and r26072 from the features/autotools_rework

branch.

Removed the configure option that allows selective disabling of individual
internal filters (fletcher32, shuffle, etc.).

This feature mucked up the code with a lot of #ifdefs, saved very little space,
and was not scalable to a general scheme for library size reduction. We've
decided to remove the feature while we investigate a more general scheme for
decreasing the library size.

Part of: HDFFV-9086

Tested on: h5committest
