…prensenting length in core functions instead of signed int in order to prevent possibly existing overflows for crafted requests. This should also fix buffer overflows in the case someone run that software on a 16 bit x86 with an already supported ᴏꜱ.

I took care to no use size_t when the signing bit might be required (at least if I didn’t mistake).
This adds an additional (but probably unnecessary) safeguard. As well fix probable issues for 16 bits x86 machines (in the case they use an ᴏꜱ already supported by exim) .
At least this doesn’t hurt (until all return values of
malloc()are checked which is something I fixed too).Only core lib functions and the variables that use them are covered by this change (definitely unnecessary for the others). But I can add them too.
If despite testing I did something wrong, _please notice me_ of course.
