[svn-r26395] Merges r26329 from trunk

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.

Fixes: HDFFV-9086

Tested on: h5committest
