Fix manual noverlay tests

* test/manual/noverlay/Makefile.in: Add copyright notice.
(LIBS): Rename...
(PACKAGES): ...to this, to avoid confusion with Autoconf's LIBS.
All uses changed.
(CFLAGS): Break out -I flag...
(CPPFLAGS): ...into this new variable.
(LDFLAGS): Rename...
(LDLIBS): ...to this, which is expected to hold -l flags.
(top_builddir): New variable.
(EMACS): Define in terms of it.
(.PHONY): Add clean, distclean, and perf targets.
(have-libcheck): Remove redundant target.  All uses updated.
(itree-tests.o): Remove redundant dependency on its source file.
(itree-tests): Remove redundant (and uncompilable) rule.

* test/manual/noverlay/check-sanitize.sh: Use /usr/bin/env.  Add
copyright notice.  Enable pipefail option, to propagate itree-tests
exit status to caller.  Fix typo in usage message.  Strip less
information from Check's error messages.

* test/manual/noverlay/emacs-compat.h: Add copyright notice.
Include stdlib.h.
(emacs_abort, eassert): Consistently use EXIT_FAILURE.
(eassume): Define when necessary.

* test/manual/noverlay/itree-tests.c: Add copyright notice.  Include
standard headers before third-party ones.  Use most narrowly
applicable ck_assert* macro for the types being checked,
e.g. ck_assert_ptr_* macros for pointer values.  Replace removed
names and APIs with current ones, e.g. the itree_node field 'color'
is now called 'red'.  Ensure preconditions of itree API are
satisfied before use, e.g. itree_node otick being set appropriately
before insertion, or global iterator being initialized
before (implicit) use (bug#58976).  Make all functions static.
(DEF_TEST_SETUP): Remove all instances, replacing with...
(test_insert1_setup, test_insert2_setup, test_remove1_setup)
(test_remove2_setup): ...these new test fixtures.
(A, B, C, D, E, N_05, N_10, N_15, N_20, N_30, N_40, N_50, N_70)
(N_80, N_90, N_85, N_95): Define as static variables rather than
macros.
(test_get_tree4): Remove, inlining salient parts.
(shuffle): Move closer to users.
(test_create_tree): Accept itree_nodes as argument instead of
dynamically allocating them.  All callers changed.
(FOREACH): Remove unused macro.
(N_BEG, N_END): Define in terms of itree_node_begin and
itree_node_end, respectively.
(test_gap_insert_1, test_gap_insert_2, test_gap_insert_3)
(test_gap_insert_5, test_gap_insert_7, test_gap_insert_11): Use
test_setup_gap_node_noadvance.
(basic_suite): Group unit tests into test cases and fixtures.  Run
previously forgotten test_insert_14.
(main): Run suite as CK_ENV to allow specifying desired verbosity in
the environment.
