Fix actors at action 0 executing the action C code protion in gameexec.c.

The bug was introduced with SAMESIZE_ACTOR_T enabling in r2208.
This fixes being unable to read the messages in A.Dream* by zykov eddy.

Lunatic: safety tweaks, expose more stuff

Arrays inside structs must not be accessible, since they're not bound-checked
by the FFI. Therefore, we flatten them into repeated scalar fields and need
to write accessor functions later.

When teleporting silently, also set g_player[].ps->bobposx/y to the new position

This fixes an integer overflow when a distance is calculated later.

Integer Overflow Offensive continued: first round of -ftrapv - cleanness.

That is, "clang -ftrapv" builds don't abort almost immediately after entering
a level.

There are various classes of overflow bugs, needing different handling:
 - Some texture mapping code was written with signed integer wrapping semantics
   in mind.  In some places, we're able to get away with unsigned casts.
 - sometimes, we really need a wider range, like when calculating distances or
   dot products
 - negating INT_MIN.  Here, we cast to int64_t temporarily.  Note that if the
   result is 32-bit wide, no 64-bit code may actually need to be generated.
 - shifting into a signed integer's sign bit.  We cast to uint32 here.
 - in hitscan(), at the "abyss crash prevention code" comment, it's clearly
   the other code that is better...

This is not merely done for pedantry, but rather makes it easier to track down
overflow bugs having a real impact on the game.
