From: Johannes Schindelin <johannes.schindelin@xxxxxx>
With this change, the `index_state` struct becomes the new home for the
flag that says whether the fsmonitor hook has been run, i.e. it is now
per-index.
It also gets re-set when the index is discarded, fixing the bug where
fsmonitor-enabled Git would miss updates under certain circumstances.
