Merge #14636: Avoid using numeric_limits for sequence numbers and lock times

Browse Source 
535203075e Avoid using numeric_limits for sequence numbers and lock times (Russell Yanofsky)
bafb921507 Remove duplicated code (Hennadii Stepanov)
e4dc39b3bc Replace platform dependent type with proper const (Hennadii Stepanov)

Pull request description:

  Switches to named constants, because numeric_limits calls can be harder to read and less portable.

  Change was suggested by jamesob in https://github.com/bitcoin/bitcoin/pull/10973#discussion_r213473620

  There are no changes in behavior except on some platforms we don't support (ILP64, IP16L32, I16LP32), where `SignalsOptInRBF` and `MutateTxAddInput` functions would now work correctly.
