This changeset basically replaces `ruby_xmalloc(x * y)` into
`ruby_xmalloc2(x, y)`. Some convenient functions are also
provided for instance `rb_xmalloc_mul_add(x, y, z)` which allocates
x * y + z byes.
Cfuncs that use rb_scan_args with the : entry suffer similar keyword
argument separation issues that Ruby methods suffer if the cfuncs
accept optional or variable arguments.
This makes the following changes to : handling.
* Treats as **kw, prompting keyword argument separation warnings
if called with a positional hash.
* Do not look for an option hash if empty keywords are provided.
For backwards compatibility, treat an empty keyword splat as a empty
mandatory positional hash argument, but emit a a warning, as this
behavior will be removed in Ruby 3. The argument number check
needs to be moved lower so it can correctly handle an empty
positional argument being added.
* If the last argument is nil and it is necessary to treat it as an option
hash in order to make sure all arguments are processed, continue to
treat the last argument as the option hash. Emit a warning in this case,
as this behavior will be removed in Ruby 3.
* If splitting the keyword hash into two hashes, issue a warning, as we
will not be splitting hashes in Ruby 3.
* If the keyword argument is required to fill a mandatory positional
argument, continue to do so, but emit a warning as this behavior will
be going away in Ruby 3.
* If keyword arguments are provided and the last argument is not a hash,
that indicates something wrong. This can happen if a cfunc is calling
rb_scan_args multiple times, and providing arguments that were not
passed to it from Ruby. Callers need to switch to the new
rb_scan_args_kw function, which allows passing of whether keywords
were provided.
This commit fixes all warnings caused by the changes above.
It switches some function calls to *_kw versions with appropriate
kw_splat flags. If delegating arguments, RB_PASS_CALLED_KEYWORDS
is used. If creating new arguments, RB_PASS_KEYWORDS is used if
the last argument is a hash to be treated as keywords.
In open_key_args in io.c, use rb_scan_args_kw.
In this case, the arguments provided come from another C
function, not Ruby. The last argument may or may not be a hash,
so we can't set keyword argument mode. However, if it is a
hash, we don't want to warn when treating it as keywords.
In Ruby files, make sure to appropriately use keyword splats
or literal keywords when calling Cfuncs that now issue keyword
argument separation warnings through rb_scan_args. Also, make
sure not to pass nil in place of an option hash.
Work around Kernel#warn warnings due to problems in the Rubygems
override of the method. There is an open pull request to fix
these issues in Rubygems, but part of the Rubygems tests for
their override fail on ruby-head due to rb_scan_args not
recognizing empty keyword splats, which this commit fixes.
Implementation wise, adding rb_scan_args_kw is kind of a pain,
because rb_scan_args takes a variable number of arguments.
In order to not duplicate all the code, the function internals need
to be split into two functions taking a va_list, and to avoid passing
in a ton of arguments, a single struct argument is used to handle
the variables previously local to the function.
After 5e86b005c0, I now think ANYARGS is
dangerous and should be extinct. This commit deletes ANYARGS from
rb_ensure, which also revealed many arity / type mismatches.
* dir.c (join_path_from_pattern): add the last slash for directory
matching.
* test/ruby/test_dir.rb (test_glob_recursive_directory): add a test
for above.

Braces were expended before ruby_glob0(). This caused to call
replace_real_basename() for same plain patterns repeatedly.
Move blace expansion into glob_helper() in ruby_glob0() to reduce
replace_real_basename() call.
This fix changes the order of glob results.

On further examination, Dir.chdir with a block from multiple
threads is thread-unsafe given our use of the chdir_blocking and
chdir_thread global variables.
This bug was only introduced in r60583 so not part of any stable
release.
Dir.chdir without a block can still make senses in a MT context
as only one thread could be cwd-sensitive and other threads do
not care which directory they're in.
* dir.c (dir_chdir): keep GVL here
(dir_s_chdir): release GVL if no block given

Support nanosec file timestamp on Windows 8 or later.
Original patches are written by kubo (Kubo Takehiro).
Windows 7 and earlier also supports nanosec file timestamp, but it's too
accurate than system time. so, this feature is disabled on such versions.

Using readdir(3) without any locking causes thread-safety
problems if directory streams get shared between threads. On
ancient platforms, readdir(3) may have thread-safety problems
even on different directory streams.
Using readdir_r(3) is not viable, either, as it's deprecated
due to name overflow problems.
So for now, rely on GVL as in previous Rubies and perhaps
consider per-"struct dir_data" mutexes for modern platforms
which allow concurrent calls to readdir(3) on different
directory streams.

This avoids blocking the entire VM when operating on slow or
