Subject: [PATCH 2/5] Engine: extend subscriptions state to account for
multiple client subscriptions to the same path
Remove accidental whitespace change
Simplify branching in watch_fast and unwatch_fast
Indentation fixes
Store the subscription counts directly in the hash table pointer instead of mallocing ints
Add documentation comments for new utility functions
