Stop lying about H5S_t const-ness #1209
Conversation
Hyperslabs can be reworked inside several H5S callbacks, making H5S_t non-const in some places where it is marked const. This change switches these incorrectly const H5S_t pointer parameters and variables to non-const where appropriate.
This fixes the majority of the pernicious const warnings in H5S and H5D. I left a few stragglers so that this PR focused only on a single const case. |

This is the one case where there wasn't much I could do. Being honest about const here prevents us from using this function as a cmp callback so I added the comment and silenced the cast.
There's no real code changes here, btw - this is all about removing 'const' where it's lying. |

LGTM.
