Nikolaj Bjorner 0a7e003709 this one is for you Nuno 
- pull request might have new bugs given that build is broken.
- this test doesn't expose race conditions under simple tests, yet. It is a starting point.
- run under cuzz (app-verifier) should expose races, this is what it was made for.

zstring: fix encode rountrip for '\' as printable ASCII (#5120) 
This fixes encode roundtripping for all printable ASCII characters.
In particular, this now leaves a plain '\' untouched by the
encoding logic, instead of converting it to escaped hex-digits.
It also adds unit testing covering this specific zstring encoding
property, in order to avoid future regressions.
