$ GEM_HOME=/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/gems/2.6.0/ bundle
There was an error creating `/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/gems/2.6.0/bundler.lock`.

Since `Gem.open_file` no longer locks the target file and is same as
`File.open` now, simply `Gem.read_binary` should read in binary mode.
Also the body of `Gem.write_binary` is same as `File.binwrite`.

There's an issue when multiple processes try to write the same binstub.
The problem is that our file locking mechanism is incorrect because
files are truncated _before_ they are locked. So it can happen that:
* Process A truncates binstub FOO.
* Process B truncates binstub FOO.
* Process A writes binstub FOO for gem BAR from the beginning of file.
* Process B writes binstub FOO for gem BAZ from the beginning of file.
If binstub FOO for gem BAR is bigger than binstub FOO for gem BAZ, then
some bytes will be left around at the end of the binstub, making it
corrupt.
This was not a problem in our specs until the spec testing binstubs with
the same name coming from different gems changed from using gems named
"fake" and "rack" to using gems named "fake" and "myrack". Because of
the difference in gem name length, the generated binstub for gem
"myrack" is now longer, causing the above problem if binstub for gem
myrack is written first.
The solution is to make sure when using flock to always use modes that
DON'T truncate the file when opening it. So, we use `r+` if the file
exists previously (it requires the file to exist previously), otherwise
we use `a+`.

This patch adds `--target-rbconfig` option to specify the rbconfig.rb file
for the deployment target platform. This is useful when cross-compiling
gems. At the moment, this option is only available for `extconf.rb`-based
extensions.

If a gem is required circular, and there are unresolved specs depending
on it, we may end up in an activation conflict.
The solution is to not try to activate unresolved gems when requiring a
default gem, regardless of it having already been activated or not.

This is based on the list in Gem::UpdateSuggestion and Bundler::Fetcher;
these have similar purposes (determining whether/what CI we're executing
in), and can benefit from being combined and updated (they're both
slightly out of date).
Noteable changes:
* We'll consider ourselves to be on a CI in more cases - if CI_NAME or
TASKCLUSTER_ROOT_URL are set specifically, since those represent two
cases that were either overlooked or are no longer covered by the
existing implementation. (Or possibly TaskCluster still does provide
RUN_ID, but failed to document it)
* We will notice/track a few additional services in ci_strings (cirrus,
dsari, taskcluster), stop tracking 'snap' (they went under in 2017),
and update buildbox to buildkite (they've been called that for 8
years, and the BUILDBOX envs have been deprecated for 3).
* We'll also sort/uniq/downcase the values (all of which only matter
because of the special case of CI_NAME).
