fa09cb41f5 refactor: Remove unused LogPrint (MarcoFalke)
3333415890 scripted-diff: LogPrint -> LogDebug (MarcoFalke)

Pull request description:

  `LogPrint` has many issues:

  * It seems to indicate that something is being "printed", however config options such as `-printtoconsole` actually control what and where something is logged.
  * It does not mention the log severity (debug).
  * It is a deprecated alias for `LogDebug`, according to the dev notes.
  * It wastes review cycles, because reviewers sometimes point out that it is deprecated.
  * It makes the code inconsistent, when both are used, possibly even in lines right next to each other (like in `InitHTTPServer`)

  Fix all issues by removing the deprecated alias.

  I checked all conflicting pull requests and at the time of writing there are no conflicts, except in pull requests that are marked as draft, are yet unreviewed, or are blocked on feedback for other reasons. So I think it is fine to do now.
