Nathan Marley 41680f4d94 small cleanup in a few places (#2058) 
* move nStart closer to used and initialize it

* Quells warning displayed with `-Wmaybe-uninitialized` flag

* remove unused mnEntries vectors

* add devnet magic bytes to mininode.py

* remove unused governance-misc.h file

* remove old TODO comments

* replace map count/insert w/emplace in instantx.cpp

This feels like an optimization, something about:

```
if map.count(key)
     return false
else
     insert(pair)
     return true
```

... just feels icky. Plus, `vote.GetMasternodeOutpoint()` is only called
once. The previous version might be slightly more readable, however.

* Revert "replace map count/insert w/emplace in instantx.cpp"

This reverts commit d7f876e863.

// DetectShutdownThread() then exits, which causes AppInit() to
// continue (it .joins the shutdown thread).
// Shutdown() is then
// called to clean up database connections, and stop other
// threads that should only be stopped after the main network-processing
// threads have exited.
//
// Note that if running -daemon the parent process returns from AppInit2
// before adding any threads to the threadGroup, so .join_all() returns
// immediately and the parent exits from main().

// Shutdown for Qt is very similar, only it uses a QTimer to detect
// fRequestShutdown getting set, and then does the normal Qt
// shutdown thing.
