Add leveldb: prefix to leveldb debug logging lines.
leveldb debug messages come in various scary flavors such as:

    2017-11-30 08:26:31 leveldb: Recovering log #26
    2017-11-30 08:26:31 leveldb: Level-0 table #28: started
    2017-11-30 08:26:31 leveldb: Level-0 table #28: 597 bytes OK
    2017-11-30 08:26:31 leveldb: Delete type=0 #26
    2017-11-30 08:26:31 leveldb: Delete type=3 #24

so it's reasonably important to mark them as coming from leveldb
internals and not from consensus validation wallet or such.

(this only affects `-debug=leveldb` or `-debug=1` otherwise you won't
see them in the first place)

  so it's reasonably important to mark them as coming from leveldb internals and not from consensus validation wallet or such.
  This is consistent with the `libevent:` prefix for libevent messages.

  (this only affects `-debug=leveldb` or `-debug=1` otherwise you won't see them in the first place)

8963b2c qt: Improve comments in WalletController::getOrCreateWallet() (Hennadii Stepanov)
5fcfee6 qt: Call setParent() in the parent's context (Hennadii Stepanov)
5659e73 qt: Add ObjectInvoke template function (Hennadii Stepanov)

Pull request description:

  The `setParent(parent)` internally calls `QCoreApplication::sendEvent(parent, QChildEvent)` that implies running in the thread which created the parent object. That is not the case always, and an internal assertion fails in the debug mode.

  Steps to reproduce this issue on master (007e15d) on Linux Mint 20 (x86_64):

  ```
