Shrink it from 1MB to 300KB. Add a diagnostic if the expansion fails
due to insufficient capacity.
300KB is required for the ship cockpit bitmap. Everything else seems to
be smaller.
User jammer1 reports that Python under MSYS2[1] reports a `sys.platform`
of `msys`. For the limited purposes Rebirth requires, this platform can
be treated as if it were `win32`. Add a mapping to apply this change
automatically, so that users do not need to set it on the command line.

enable_build_failure_summary=1 assumed that the command to display was a
list. For internal pseudo-commands, such as write_pch_inclusion_file,
the command was a string, so calling ' '.join() was incorrect. When the
output is not a list, pass it through unchanged.
Add macro cf_assert ("control flow" assert) to hint to gcc that certain
conditions are impossible. Use it to avoid generating range checks for
situations that never happen. If the event did happen, the only
consequence would be truncated UI text, rather than a correctness
problem.
The prior design was meant to allow the hook to be called instead of the
normal function, with the hook chaining to the normal function and then
performing other work as needed. This flexibility is unnecessary, and
complicates improvements elsewhere. Replace it with a hook that is
called with the result of the regular StaticObject call.
Use of the comprehensions makes the code less readable and harder to
modify. The performance benefit, if any, is in the noise. Switch to
an unpacked form.
Move it to a structure. Make all the modifiers methods. Change all
callers of those methods to pass the structure. This makes the stuck
object handling free of direct access to global game data.
Commit 07245a0bc2 added the SDL_mixer backend for MVE audio. That
commit set the length of the converted sound equal to the size of the
buffer that SDL requested as a work area. No one ever touched that
logic, until now. In SDL1, that choice worked fine. In SDL2, this
causes garbage to play after the sound, because SDL2 considers the
buffer to be defined only up to the length returned in
`SDL_AudioCVT::cvt_len`. Bytes beyond that length are undefined[1], and
in practice contain garbage. Fix the noise by setting the sound length
equal to the length returned by SDL2, so that the undefined bytes are
not treated as sound. SDL1 also maintains this length value, so no
version-specific logic is required.
