On the engine side (functions starting with L_), there are now the basic
parts like state creation and running code from strings and files.
The game and editor can add to that by e.g. loading whatever they please
into the state. Their functions start with El_ and Em_, respectively.
The Lua scripts still reside in source/lunatic, even for the common ones.
This is because they will be embedded into the binaries as bytecode or
compressed source eventually, so their location on disk will be irrelevant.

This event is useful in certain circumstances where you want to skip a menu/screen value and the design of the monster switch statement would require the M_ChangeMenu() call to be intercepted or the unwanted screen will flash for a split second.

Going to extremes to avoid code duplication like the plague, but at
least it's great to learn about the whole function environment business.

The Makefile now has separate {GAME,EDITOR}LDFLAGS, so the correct
dynamic symbol list can be specified.

... and displaying statistics afterwards. It was easier to do it this way
than porting stat.lua to C and especially adding more logic to the already
spaghetti-like demo playback code.

Also, add convenience wrapper script findmaps.sh for quickly searching for
sprites/walls/sectors satisfying a certain condition in all map files under
a given directory.

One potential use is to examine values which are clobbered by commands such as ifhitweapon/ifwasweapon.

This is mostly for debugging, since currently, Mapster32 restores sprites
not in the same order as the original sprite index order. Also, expose
this option from map2text.lua and mapdiff.sh.

Also, rewrite the mapastats iterator and the LIZTROOP hitscan timing
in terms of that.

Also fix error handling path in our_require(), i.e. when loadstring fails.

The map iterator now has init/finish capability, making it possible to
write scripts that aggregate data over multiple map files. One such example
calculates some statistics, the other loads art metadata and looks for
red walls with non-pow2 ysize tiles.

uhypsq calculates the hypotenuse using unsigned multiplication. This is
permissible since for arbitrary int32s a and b, the following holds in
two's complement arithmetic:
(int32_t)((uint32_t)a * b) == (int32_t)((int64_t)a * b)
("Signed and unsigned multiplication is the same on the bit level.")
This fixes various overflows where wall lengths for walls of length > 46340
are calculated, but does not rid us of other overflows in the same vein
(usually dot products between vectors where one point is a wall vertex and
the other a position in a sector).
