Allows to use regular constructor/destructors. And standard CPP data like string, maps, etc. Main is defined as non-movable and non-copyable for the time being. The existing creating/deleting API is kept as-is, moving to direct MEM_new/MEM_delete usages in the code is kept as a later cleanup commit. The 'ListBase' of split-by-libraries Mains has been replaced by a VectorSet. This is an unfortunate consequence of making Main a non-trivial C++ struct: it is no more guaranteed that next/prev pointers required for ListBase remain immediately at the top of the struct anymore - and on Windows they indeed don't. So move to a more modern form of storage for split-by-libraries mains, with a few other related changes to internal readfile code. WARNING: This is quite a sensitive change, extensively tested locally (including library-related changes across undos and redos, in complex production scenes).
