(MouseDown): Set that field.
(MouseUp): Clear that field.
(MouseMoved): Also test `maybe_overscroll' to ensure that a grab

Use a dedicated stack for bytecode, instead of using the C stack.
Stack frames are managed explicitly and we stay in the same
exec_byte_code activation throughout bytecode function calls and
returns. In other words, exec_byte_code no longer uses recursion
for calling bytecode functions.
This results in better performance, and bytecode recursion is no
longer limited by the size of the C stack. The bytecode stack is
currently of fixed size but overflow is handled gracefully by
signalling a Lisp error instead of the hard crash that we get now.
In addition, GC marking of the stack is now faster and more precise.
Full precision could be attained if desired.
Pass the function object and encoded arity, not the other components.
This speeds up several call paths and is necessary for improvements to
come.
* src/bytecode.c (Fbyte_code): Make a new byte code object for
