  tests: Support showing all assertion failures, not just the first one.
  
  * tests/macros.h (CONTINUE_AFTER_ASSERT): New macro.
  (test_exit_status): New variable.
  (ASSERT, ASSERT_NO_STDIO): If CONTINUE_AFTER_ASSERT is 1, set
  test_exit_status instead of aborting.
  * tests/**/test-*.{c,h,cc} (main): Instead of exiting with exit code 0,
  exit with exit code test_exit_status.
  * tests/test-spawn-pipe-child.c: Undefine CONTINUE_AFTER_ASSERT.
  * tests/uninorm/test-nf*.c: Include macros.h.
  * tests/uninorm/test-u32-nf*-big.c: Likewise.
  * tests/random*.c: Define NO_MAIN_HERE.
