Use helper for FP comparisons, use -Wfloat-equal

Direct comparison may have portability concerns because a constant may
have more precision than its counterpart.  Even a direct cast before
a comparison may not work (e.g. Math.atan2() assert with gcc -m32 still
fails even when both sides have an explicit double cast).  So use an
internal always-inline helper for float/double comparisons, which also
allows -Wfloat-equal warning to be suppressed in a single helper; add
a clang pragma option so that both gcc and clang suppress the warning.

Other changes:

* Add -Wfloat-equal warning back to the Makefile.

* Fix all internal float comparison call sites to use the helper.

* Add code policy check for probable floating point comparison
  (not very important with -Wfloat-equal enabled).

Changes to compile CBOR extra as built-in

* Add minimal CBOR config options.

* Add 'CBOR' built-in YAML metadata.

* Add a public C API for CBOR.

* Remove examples/cmdline support for extras/cbor, use built-in CBOR
  instead.

* Makefile, dist/tools changes.

* Rewrite CBOR extra to use Duktape internal helpers, also some related
  refactoring.

Fix -fsanitize=undefined warnings

Add internal helpers to deal with undefined behavior cases explicitly.
When DUK_USE_ALLOW_UNDEFINED_BEHAVIOR is set, skip the (almost always
unnecessary) explicit checks to improve footprint and performance.

Also split duk_util_misc.c into a few better scoped files.
