Since macOS 13, CFString family API used in
`rb_str_append_normalized_ospath` may internally use Objective-C classes
(`NSTaggedPointerString` and `NSPlaceholderMutableString`) for small strings.
On the other hand, Objective-C classes should not be used for the first
time in a `fork()`'ed but not `exec()`'ed process. Violations for this rule
can result deadlock during class initialization, so Objective-C runtime
conservatively crashes on such cases by default.
Therefore, we need to use CFString API to initialize Objective-C classes
used internally *before* `fork()`.

This page provides an overview of IO streams. It's meant to be linked to from many other doc spots. In particular it will be linked to from many places in ARGF, File, IO, and StringIO.

Use macro instead of a static functon. This isn't very amusing but
doing this wihtout a macro (is possibe but) seems just too much.

`HAVE_FTRUNCATE` has been added 14 years ago.

If we are expanding the string or only stripping extra capacity
then coderange won't change, so clearing it is wasteful.

Otherwise it's way too easy to confuse it with US_ASCII.

Also adds section "Example Files" that explains assumptions about example files. I'm using t.txt already, and I'm pretty sure I'll need t.dat (binary data). I don't know whether I'll need t.rus (Russian text).

Allocating a string of length MAXPATHLEN and then shrinking the string
is inefficient when the resulting path is short. Preallocating a large
string is also a problem for Variable Width Allocation since we can't
easily downsize the capacity.
I ran the following benchmark:
```ruby
Benchmark.ips do |x|
{
"empty" => "",
"short" => "a/" * 10,
"medium" => "a/" * 100,
"long" => "a/" * 500
}.each do |name, path|
x.report(name) do |times|
i = 0
while i < times
File.expand_path(path)
i += 1
end
end
end
end
```

I used this regex:
(?<=\[)#(?:class|module)-([A-Za-z]+)-label-([A-Za-z0-9\-\+]+)
And performed a global find & replace for this:
rdoc-ref:$1@$2

After the change to use realpath on loaded features, Solaris CI
started failing in test_no_curdir (which tests behavior for running
ruby without a working directory).
I was able to trace the problem to the following call chain:
rb_call_inits->Init_Thread->Init_thread_sync->rb_provide->
get_loaded_features_index->rb_check_realpath->rb_dir_getwd_ospath->
ruby_getcwd
This will throw an exception, but because Ruby hasn't been fully
initialized at the point the exception is thrown, it just exits
with a status of 1.
The bug here is that rb_check_realpath should not raise an
exception, it should return nil. This bug is hit on Solaris
because Solaris uses the realpath emulation instead of native
realpath, and the realpath emualation raised instead of
returning nil if the mode was RB_REALPATH_CHECK. Use rb_rescue
in the realpath emulation if the mode is RB_REALPATH_CHECK, and
swallow any exceptions raised and return nil.
