54721d7461 Make ksqrt take uint32_t, add helper function uint32_t uhypsq(int32_t,int32_t).
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).

9431207c74 Lunatic: ksqrt, with timing and value test.
The latter shows that "int32_t ksqrt(int32_t)" also copes with values in the
range INT32_MIN..-1, effectively interpreting them as uint32_t (i.e. adding
2**32).  However, this should not be relied on from CON.

2d324c97be 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.

5bdbd2eda5 Lunatic/LT: provide the predefined labels in con_lang, add "strict" from luajit.
The latter is only for development, since the embedded version already has a
undeclared-var-reference handling similar to that.  Also fix parm2memberpat.

59fa419506 Lunatic: pack actor/move parameters into t_data, which is enlarged to 14 elements.
(LUNATIC build only.)
Also, a minor problem is identified.  sizeof(actor_t) is 124 on 64-bit platforms,
while the expected size is 128 bytes.  This needs to be corrected whenever the
next savegame version bump happens.

8f8bb68ace Rename ud.clipping to ud.noclip internally for sanity.
This might now be even more confusing for users reading both the source
and CON code (where the access is necessarily still via '.clipping'),
but at least reading the source now makes sense :P
