615c1adfb07b9b466173166dc2e53ace540e4b32 refactor: wrap CCoinsViewCursor in unique_ptr (James O'Beirne)
Pull request description:
I tripped over this one for a few hours at the beginning of the week, so I've sort of got a personal vendetta against `CCoinsView::Cursor()` returning a raw pointer.
Specifically in the case of CCoinsViewDB, if a raw cursor is allocated and not freed, a cryptic leveldb assertion failure occurs on CCoinsViewDB destruction (`Assertion 'dummy_versions_.next_ == &dummy_versions_' failed.`).
This is a pretty simple change.
