When attempting to require a file without an extension that has
already been required or provided with an .so extension, only
look for files with an .rb extension. There is no point in
trying to find files with an .so extension, since we already
know one has been loaded.

Previously, attempting to require such a file scanned the load
path twice, once for .rb and once for .so.  Now it only scans
once for .rb.  The scan once for .rb cannot be avoided, since
the .rb file would take precedence and should be loaded if it
exists.

This revert is to confirm whether the commit is the cause.
If the failures consistently occur after this revert, I'll
reintroduce the commit.

Document that only first 9 numbered capture groups can use the \n
backreference syntax.  Document \0 backreference.  Document \K anchor.

The previous implementation could result in a returned
float that is 1/(10**ndigits) too low.  First try adding
one before dividing, and if that results in a value that is
greater than the initial number, then try the original
calculation.

Spec added for ciel, but the issue doesn't appear to affect
ciel, at least not for the same number.  If the issue does
effect ciel, a similar fix could probably work for it.

Fixes [Bug #18018]

VM patch from wanabe.

Test based on example from buzztaiki (Taiki Sugawara).

Test fails when compiles with -DRUBY_DEBUG, as that can
can use rb_bug instead of NoMemoryError, which doesn't
allow testing this case. Test also fails on MingW, as
RangeError is used instead of NoMemoryError. Skip the
test in either case.

Detect Unicode ranges and loop over them.
This fixes issue #18028.

Deal with the issue that the emoji files in emoji/13.1 have Unicode
Emoji version 13.1, but at the same time the files in 13.0.0/ucd/emoji
are still at Emoji version 13.0. Specifically:
- Add a version attribute to TestEmojiBreaks::BreakFile
- Take the version for emoji-variant-sequences.txt from the Unicode
  version, removing the last two characters.
- Improve information in exceptions for file name and version mismatches.

If the thread termination invokes user code after `th->status` becomes
`THREAD_KILLED`, and the user unblock function causes that `th->status` to
become something else (e.g. `THREAD_RUNNING`), threads waiting in
`thread_join_sleep` will hang forever. We move the unblock function call
to before the thread status is updated, and allow threads to join as soon
as `th->value` becomes defined.
