At this point, or minimum required glibc is implicitly 2.18, due to thread_local support being enabled by default. However, users can disable thread_local support to maintain 2.17 ccompat for now, which is currently done in the Guix build.

These checks were added in bitcoin#4339, (see also bitcoin#4081), to test our back-compat stubs, however, those stubs no-longer exist (bitcoin#22930), meaning that these checks are now just testing some specific standard library behaviour, without a particular rationale, or reason, compared to any other standard library functions we use. There has also been some discussion about the sanity checks in the context of the libbitcoinkernel refactoring, see bitcoin#25065 (comment). Removing the checks removes the need to worry about atleast the glibcxx checks. Also remove the list of check from the doc in init.h, because it is incomplete, and anyone who wants to know what checks are included can look at the function.

This removes our glibc backwards compatibility code (glibcxx sanity checks remain), which is no-longer used for release builds.
With these changes our minimum required glibc remains at 2.17, as Guix builds are done with
--disable-thread-local.Guix builds:
