54a5a21[MOVEONLY] Turn CScript::GetOp2 into a function and move to cpp (Pieter Wuille)6a7456a[MOVEONLY] Move CSCript::FindAndDelete to interpreter (Pieter Wuille)33a8ecfDelete unused non-const-iterator CSCript::GetOp overloads (Pieter Wuille)2fb168bMake iterators in CScript::FindAndDelete const (Pieter Wuille) Pull request description: This PR moves `FindAndDelete` and `GetOp2` out of CScript (the first is only used inside the interpreter and moved there, the second does not actually depend on any script specifics and works on any vector). Furthermore, all non-const-iterator versions of GetOp are replaced by const ones, removing a number of methods in the process. The longer term goal here is making the script interpreter independent from the CScript representation. Note for reviewers: both `FindAndDelete` and `GetScriptOp` are consensus critical.
