clean up CMake code (#5182) 
* CMake: simplify FindGMP.cmake

Remove printing of all the different variables, and let FPHSA output the library
name. Add an imported target, which bundles the library and the include
directories for easier usage.

* fix build: vector::c_ptr() now is vector::data()

* CMake: use Threads::Threads imported module

Otherwise the setting of THREADS_PREFER_PTHREAD_FLAG has no effect.

* CMake: remove needless policy setting

The minimum required version is CMake 3.4, where these policies are already set
to new because they were introduced earlier.

* CMake: remove needless variable expansion

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.

get rid of threads in the scoped_timer thread pool prior to forking, on non-Windows (#4833) 
* on POSIX systems, fork() is dangerous in the presence of a thread
pool, because the child process inherits only the thread from the
parent that actually called fork().

this patch winds down the scoped_timer thread pool in preparation for
forking; workers will get freshly created again following the fork
call.
