Merge bitcoin/bitcoin#25115: scripted-diff: replace non-standard fixed width integer types (`u_int`... -> `uint`...)

672d49c863fd6b0f096f166aeb3504f51dfa7d19 scripted-diff: replace non-standard fixed width integer types (`u_int`...` -> `uint`...) (Sebastian Falbesoner)

Pull request description:

  Fixed width integer types prefixed with `u_int` are not part of C++ (see https://en.cppreference.com/w/cpp/types/integer), so it's better to avoid and replace them with their standard-conforming counterparts. (For those interested in history, according to one theory those u_int... types have been introduced by BSD: https://stackoverflow.com/a/5163960, http://lists.freedesktop.org/archives/release-wranglers/2004-August/000923.html).
