* Prevents game occasionally seemingly hanging when moving to new submaps

The reason for the previous problem was an infinite loop caused by:
1. `map::spawn_monsters_submap` for-loops the list of `current_submap->spawns`
2. for every spawned monster, it calls `monster::on_load`
3. `monster::on_load` calls `monster::try_reproduce`, which in turn calls
   `map::add_spawn`
4. So a new spawn is added, thus invalidating the iterator used in step 1
5. Undefined behavior caused by using invaliated iterators.

On my compiler (gcc 13.2.0), the above problem had the following effect:
* The reference `spawn_point &i` pointed to something totally different, so
  that in particular, `i.count` had garbage values
* Instead of `i.count` being reasonable values such as `3` or `1`, the above
  undefined behavior made it have values such as `925969776` or `-632214304`
* `i.count` is the upper bound for the inner for-loop in
  `map::spawn_monsters_submap`, so depending on the garbage value, it might
  seem like an infinite loop.

This commit instead changes the loop in step 1 above so that it explicitly
*not* uses iterators, but instead old-fashioned indexed loop. The intention
with the change is to allow other parts of the code to add items to the vector
`current_submap->spawns` while we are iterating it here. If new items are
added, they will be handled in later steps of the loop.

Prevents segfault that previously happened when pouring liquid to ground

```

The problem before was that the reference to `target` in
`unload_activity_actor::unload` was an invalid reference. This was
caused by:
  1. `unload_activity_actor::finish` calls `act.set_to_null()`.
  2. That sets the player activity to `null` type (=no current activity)
  3. `unload_activity_actor::unload` is `static`, and takes `target` as
     a reference.
  4. `::unload` calls `Character::add_or_drop_with_msg` which leads to
     call chain: `liquid_handler::consume_liquid` -> `get_liquid_target`
     -> `choose_adjacent` -> `choose_direction`
     -> `temp_hide_advanced_inv` -> `advanced_inventory::temp_hide`
     -> `advanced_inventory::do_return_entry`
  5. `advanced_inventory::do_return_entry` assigns a new
     `ACT_ADV_INVENTORY` activity. This invalidates the previous
     `unload_activity_actor` because of pt 2 above.
  6. When static method `unload_activity_actor::unload` resumes after
     its call to `add_or_drop_with_msg`, the reference to `target` is
     invalid because of pt 5.

This commit attempt to fix the issue with invalidated `target` reference
by copying its value before invalidating the activity.

Prevents segfault that could previously occur if the item being repaired

item could burn up in a fire, etc.

Prevents division by zero crash when displaying widgets with defined
break levels.

Example of where previous crash from div-by-zero happened:
* Provided save used the `zenfs_thick_sidebar`, which includes widget
  `zenfs_mana_bar_14_no_label` that defines break levels.
* When running the provided save, mana value is usually at `v=201` with
  `min=0` `max=201`.
* Those values are computed by `known_magic::max_mana` where internal
  values are `bionic_penalty=999` `mana_base=1000` `int_bonus=200`.
* But when int falls (because of tiredness), then
  `known_magic::max_mana` will return `0` because `int_bonus=-100`.
* This leads to `_var_max=0` in `widget::value_color` and thus
  `var_range=0` which causes the div by zero.

Backtrace of previous crash beng fixed:
```

Prevents crashes that previously happened from using references to
`explosion_data` that had been invalidated.

The problem before happened when killing "unfolded impossibility" in
LIXA facility with a grenade, since this monster runs an eoc that
switches maps. That led to `explosion_handler::process_explosions` being
called twice recursively. First invocation iterates references, and the
second invocation might append to the vector, and most certaily will
clear the vector, thus invalidating references for the first invocation.

Example crash being fixed by this commit, notice how
`explosion_handler::process_explosions` occurs twice in the callstack:

Prevents referencing `visibility_cache` using out-of-bounds array
indexes such as negative values. Using out-of-bound indexes for this
array previously caused crashes when compiled with
`-D_GLIBCXX_ASSERTIONS`.

The function `pixel_minimap::render_critters` is, for example, called
with `center=(64,59,-5)`, which gives `start=(4,-1)` and then
`p=(4,-1,-5)`, which previously crashed because
`visibility_cache[p.x][p.y]` then gives a negative array index. Such
values were seen when peeking using `X` at a submap boundary.
