A number of test features need to do pretty complicated string printing where it may not be possible to rely on a single preallocated string with parameters.
So provide a library for constructing the string as you go similar to C++'s std::string.

Is there any reason why we can't use the seqfile API for this? These both share a similar goal, formatting strings into a buffer to be read later. Maybe some new APIs would be needed to extract the buffer differently, but I hope we could share the code.
If it can't be used, can you please add the reasoning to the commit text here?
