Codechange: Optionally allow passing state to GUIList sorter function.

GUIList sorter functions can currently only use global state, which makes per-window-instance sorting difficult.

Codechange: automatic adding of _t to (u)int types, and WChar to char32_t

Codechange: [core] Implement SmallVector using std::vector

The public and protected interface to SmallVector are unchanged
SmallVector now requires that items be default constructible
This isn't an issue since some contained items were previously created
uninitialized.

Temporary default constructors are added to the following structs
- SmallPair
- SmallStackItem
- GRFPresence

Where vector<bool> is required, transition immediately to std::vector
to avoid returning proxy object references.

(svn r13575) -Codechange: Move small vector to core since it fits better in there
-Codechange: convert smallvector from struct to class

(svn r13535) -Codechange: Protect GUIList internals
-Fix: VL_FIST_SORT should be set after list rebuild too

(svn r13516) -Codechange: Move MemCpyT to a fitting core header
-Codechange: Split the sorting code from the sortlist to an appropriate header

(svn r13275) -Fix: sort lists with 2 items, too
-Fix: reset VL_RESORT and resort timer even when no sort was needed
