prerequisite of #2802

This pull request ports the files:

• replace.go
• replace_test.go

I added some tags on the code with the hope it will help to review the code and to launch discussion if neccessary.
I could after remove these changes

// Custom code: XXX_Some_Explanation

more than these tags, which are still good, i'm looking for tooling which can help us compare go stdlibs and gno stdlibs

there was a pr by an external contributor which was stopped at one point: #1425

if you want, you can continue his work, minding the unaddressed comments i made - i'd highly appreciate it ;)
