ISSOtm d43ef53745 Remove unreachable bank range check
The only case where it is not generated by our own code
(which we ought to be `assume`ing is correct) is when the bank
is used-specified, but that is caught by an earlier check.

ISSOtm ef709fade6 Refactor and fix sect packing's bank iteration
Moving both pieces of related code together, as it were.
This also ends up changing the behaviour of scrambling,
where sections could “leak” out of the scrambling's bank pool
and resume being placed normally.

We have discussed it offline, and decided that this was a bug.
The test suite has been updated accordingly, which even gives
the occasion to move this test from a special case to the main
generic loop!

ISSOtm 8685bcbfbf Refactor all scrambling-related dispatch into a single func
Yay for (poor man's) pattern matching! 🦀

Trying to keep code grouped together well.

ISSOtm f234796428 Avoid allocating for our linkdef names (#2111)
This reverts a change introduced in fd78a9ae8, though it wasn't that commit's main point
so I'm feeling okay with undoing that.

This feels like an overkill change, using a static string is good enough for this
since we never modify this. I have considered using `string_view` instead, to have
the best of both worlds, but that's not NUL-terminated so our print functions
get a little grumpy.

This would happen for any such section of non-zero size.

Rangi aa657cd481 Make array buffers for snprintf just large enough for their uint32_t and uint16_t types
Note that `bank` can store 9 bytes (8 digits plus NUL terminator)
even though `section.bank` should never go above 16-bit (4 digits).

Rangi 589616338f Remove redundant conditional check (#2099)
If `nbBanks > 1` is true, then `sectionTypeInfo[type].firstBank !=
sectionTypeInfo[type].lastBank` must also be true, so checking
whether either is true is unnecessary.

(On the other hand, if `nbBanks == 1`, then we might still have
`sectionTypeInfo[type].firstBank != sectionTypeInfo[type].lastBank`,
since only one of many valid banks for `type` could be in use.)

Rangi f8a1da71c1 Only sort generated palette colors by PLTE order for indexed PNG images
Non-indexed images can still have a PLTE chunk. We should use
`sortRgb` instead of `sortIndexed` for them, since their pixels' colors
may not all be present in the PLTE chunk and would be unsortable.

Max Freedom Pollard 631ef003e7 Avoid signed overflow in RGBLINK's +, -, and * (#2060)
RGBASM computes these with unsigned arithmetic and casts back, since
signed overflow is UB in C++, but RGBLINK's RPN evaluator used `int32_t`
directly, so `src/link/patch.cpp` tripped UBSan on lines 117, 121, and
124. Share the three operators through `opmath.cpp` so both evaluators
stay in step.
