Various basecamp actions require components and tools to be consumed.

When there are choices to be made amongst these, the player is presented
with the choice between the various options in the usual way.

However, if the player cancels, the action proceeded regardless.  This
allowed the player to circumvent the consumption of the requirements.

Fix this by separating the selection of the components from the
consumption.  Now the order of events is:

- Select components and tools.
- Select NPC.
- Send NPC on mission.
- Consume components and tools.

We needed to perform the split because we need to select both the
requirements and the NPC before performing alterations to either.

Implemented by introducing a new class basecamp_action_components to
store this selection state.

* Martial Arts missing Learn Diffculty and Incorrect Bonuses

Medieval Swordsmanship and Leopard Stance were missing the learn difficulty, making them potentially easier to learn than intended.

Leopard stance's on move buff gave a flat bonus to damage instead of the intended multiplier.

Eskrima stance was giving a 200% bonus to accuracy instead of the intended +2 accuracy.

A gcc-specific warning option had been added (-Wsuggest-override).  In
theory this was guarded against being used with clang, but that didn't
work if a compilation database was built with gcc and then used with
e.g. clang-tidy.  In that situation clang would complain about the
unrecognized warning.

The suggested workaround in the DEVELOPER_TOOLING docs was to add
-Wno-unknown-warning-option, a clang option to suppress such warnings.

However, we might as well just add that option always, then we don't
need to make the -Wsuggest-override conditional and the build logic is
simplified.

Technically, gcc has no such option, but gcc doesn't complain about
unrecognized disabled warning options (unless there's another error) so
we get lucky there.  Hopefully that remains true back to our earliest
supported gcc.

This might cause problems for compiling with another compiler e.g. icc,
but the way the Makefile was written, it would have had that problem
anyway, since it was added for any non-clang compiler.

The function `are_requirements_nearby` accesses `player::backlog::front()`, which causes UB when the `backlog` list is empty.

This is usually checked by the caller, but there is at least one way to reach this function without that check:

```

#13 0x000000000132690a in npc::move (this=this@entry=0xdf1ae50) at src/npcmove.cpp:907
```

This adds a simple check within the function.

* 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 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:

…aven#75521)

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.

Gdb backtrace of previous crash being fixed:
