Restructure project layout and clean up test suite

Move sources to src/, header to inc/, and tests to tests/src/.
Update Makefiles and .gitignore for the new layout.

Refactor test harness: add crash-wrapper macros (_S_CRASH,
_S_CRASH_I, _S_CRASH_V, _S_CRASH_BUF) replacing 58 hand-written
wrappers, add shared _s_test_int_range helper eliminating duplicate
_s_test_func, add _S_RAND_ITERS constant, move srand() to main()
in all test binaries, and add Doxygen comments to test_utils.h.
