Pull request description:

  The next step of changes from #10785.

  This:
  * Adds support for enum serialization to `CustomUintFormatter`, used in `CAddress` for service flags.
  * Merges `BigEndian` into `CustomUintFormatter`, used in `CNetAddr` for port numbers.
  * Converts everything (except wallet and gui) to use the new serialization framework.

ACKs for top commit:
