This reduces the amount of memory Retroarch needs to extract a ROM file.
It will only need the size of the ROM plus 128KiB to extract the file
from the ZIP. Previously it needed as much as twice that amount if the
compression ratio was not great. This is useful on memory constrained
platforms and has no impact on platforms with plenty of memory.
Handles all cases correctly (with and without MMAP, for cores that
require fullpath or not, small and big ZIP files).
After PR #14821 , the contents of msg_hash_xx.c files are present
in the normal translation workflow. Since that time, almost all
languages have either caught up on Crowdin, or are still on such
low level of translation completeness, that removing these entries
does not harm usability.
Only Chinese Simplified and Portuguese Brazilian languages remain
in separate files, as they may still be considered an improvement
over Crowdin status.

* 🎵 Fast forward audio resampling. Solves #15160.
Previously, we avoided doing any resampling while fastforwarding based
on the assumption it was impossible to make the audio not crackle due to
both flush-to-flush timing fluctuations and timer accuracy.
However, turns out this is not the case. The audio doesn't "crackle" per
se when the timing fluctuates! It's just that the sounds don't make
sense since the time compression and decompression caused by the flush
time fluctuations mess with the audio consistency.
To work around that, we introduce a running average flush delta time
that makes sure the audio is both resampled to approximately the correct
rate and consistent.
This was tested in two settings:
- Limited rate fastforwarding (2x-4x)
- Unlimited fastforwarding
In both cases it seems to work well, but with unlimited fastforwarding
it's just high pitched and annoying, so this is probably the most useful
in the 2x to 4x range.
* Move declartion to support C89
* resampling ratio upper and lower bounds
* Add toggle for speeding up audio
