-fsanitize=fuzzer-no-link makes it workable to build a library with
fuzzing enabled, and let the fuzzing test program explicitly trigger the
fuzzing.

This allows fuzzing to trace cmp instructions to guide the fuzzing to
improve results.

Small change to improve the `polish-mbrola-1` voice.
Previously it would produce:
```
$ espeak -v polish-mbrola-1 "Wiewiórka siedzi na drzewie i je orzech."
mbrola: Warning: j-E# unknown, replaced with _-_
mbrola: Warning: E#-_ unknown, replaced with _-_
```

Now it correctly synthesizes the audio.

Corrected pronunciation of Helma which was pronounced as halma

Upstream implementation for feature request on iOS app:
https://github.com/espeak-ng/espeak-ng-ios-app/issues/40

Before the PR, espeak-ng -v it "0 items" caused a segmentation fault.

- test for #1660
- Revert "cleanup: fix code smell knownConditionTrueFalse for strlen()
>= 0"

Some warnings, some globals hunting.
Including fixes for asserts misuse (possible fatal for async in release
builds).
