For Ruby re-distributors, automatic user-install might be the right
default. Therefore printing warning about installing into user directory
is not always desirable. Let the default_user_install method be
customizable.

The `options[:user_install]` might have three states:
* `true`: `--user-install`
* `false`: `--no-user-install` and
* `nil`: option was not specified
However, this had not been respected previously and the `false` and `nil`
were treated the same. This could lead to auto user installation despite
`--no-user-install` being specified on the command line.

For now, on a small rails app I have hanging around:
```
==> memprof.after.txt <==
Total allocated: 872.51 MB (465330 objects)
Total retained: 40.48 kB (326 objects)
==> memprof.before.txt <==
Total allocated: 890.79 MB (1494026 objects)
Total retained: 40.40 kB (328 objects)
```
Not a huge difference in memory usage, but it's a drastic improvement
in total number of allocations.
Additionally, this will pay huge dividends once
https://github.com/ruby/zlib/pull/61 is merged, as it will allow us to
completely avoid allocations in the repeated calls to readpartial,
which currently accounts for most of the memory usage shown above.

Checking writability is prone to errors. For example:
$ mkdir -p foo/bar
$ chmod -w foo
$ touch foo/bar/baz # succeeds even if foo is not writable

The main purpose is to put handling of user installation into the same
place as e.g. handling the --build-root option handling. There is no
reason why the --build-root option should not prefix also paths used for
user installation.
Please note that the `util_installer` in
`test_generate_plugins_with_user_install` enforced the `:install_dir`,
which is against what user install is about.

We can install RubyGems plugin by "gem install XXX". The installed
plugin is used from the NEXT "gem ...".
For example, "gem install gem-src kaminari" doesn't use gem-src plugin
for kaminari. "gem install gem-src && gem install kaminari" uses
gem-src plugin for kaminari.
How about loading a plugin immediately when the plugin is installed?
If this proposal is implemented, "gem install gem-src kaminari" works
like "gem install gem-src && gem install kaminari".

If `bundler _<version>_` is given, I guess the most reasonable approach
is to completely skip version switching, because the user is technically
opting out of it. But since binstubs completely remove this argument
from `ARGV` after processing it, we have no way of detecting that it was
actually passed in the first place in order to skip the feature. So we
set `BUNDLER_VERSION` explicitly in this case.

When bundler parallel installer installs gems concurrently, one can get
confusing warnings like the following:
```
"[/home/runner/work/rubygems/rubygems/bundler/tmp/2/gems/system/specifications/zeitwerk-2.4.2.gemspec] isn't a Gem::Specification (NilClass instead).
```
I've got these warnings several times in the past, but I never managed
to reproduce them, and never look deeply into the root cause, but this
time a got a cause that reproduced quite frequently, so I looked into
it.
The problem is one thread reading a gemspec while another thread is
writing it. The write of the gemspec was not protected, so
`Gem::Specification.load` could end up seeing a truncated gemspec and
thus throw this warning.
The fix involve two changes:
* Change the methods that write gemspecs to use `Gem.binary_write` which
is protected by a lock.
* Fix `Gem.binary_write` to create the file lock at file creation time,
not when the file already exists after.
The realworld user problem caused by this issue happens in bundler, but
I'm fixing it in rubygems first, and then I'll backport to bundler
whatever needs backporting to fix the issue on the bundler side.

This reverts commit af604436d8141c34cb2e1e645b9b0d47bfd55a55.
The issue that led to introducing it was never reproduced. I tried to
repro with this patch and it still works just fine. Since this removal
is getting in the middle for some race conditions I'm facing, I'm
reverting the patch.
