The server relies a lot on strings, particularly concatenations.To keep the code small and fast, it involves a lot of manual handling, which requires care to prevent bugs or worse. It is one of the weak/sore points of the code base, which inspired the development of #Aligned Strings format. Now that this small library is functional, it is time to use it for real !

I'm still very annoyed by the limitation of the C preprocessor that prevents me from further streamlining and optimising the declarations of flexible strings inside functions, as I can't #define or alias words from inside a macro. But in this project, it's not a significant roadblock, so no need to resort to m4 or other dirty tricks : the system works, not as efficiently as I would love, but it's still a good progress compared to the overly "micromanaged" strings of the existing version. Moreover, this refactoring is a great opportunity to put the aligned strings library to the test of real life and even enhance it.
