libc: Implement bsearch_s(), document bsearch_b(), and add unit testsHEADmain

- Implement bsearch_s() as per §K.3.6.3.2 in C23, first specified
  in C11.  It behaves identically to bsearch(), except the callback
  is called with a third argument, context, which is passed through
  from the caller, and it also performs runtime constraint checking
  on its arguments.
- Document bsearch_b(), bsearch_s(), and add history section
- Add rudimentary unit tests for bsearch(), bsearch_b(), and bsearch_s()
