[Feature #19117]
test/runner.rb and tool/lib/test/unit/parallel.rb must use the same
settings. However, some settings were copied and pasted, while some were
added only to test/runner.rb.
This changeset creates tool/test/init.rb for all settings of test-unit,
which is loaded not only by test/runner.rb but also
tool/lib/test/unit/parallel.rb.
Background: the GEM_HOME environment variable was removed in
test/runner.rb, which prohibit `require "rake"` (note that rake is a
bundled gem). However the parallel mode didn't refrect this setting,
i.e., `require "rake"` was allowed.
This leads to an inconsistency, which actually affected a test test
defines s test class *only when* `require "rake"` is successful.

to @__passed__, @@__current__.
@passed is redefined in a few test suites, and this could lead to bugs.
Also rename @options (Runner#options) to @__runner_options__, which is
only used in make test-tool anyway.
This test skipped sometimes due to failure to load 'rake/packagetask'.
This is due to manipulation of $LOAD_PATH by other rubygems tests. If
rake is loaded before any rubygems tests run, then it works fine.
To reproduce the skipping behavior:
$ make test-all TESTOPTS="-j6 --test-order=sorted test/rubygems/test_*.rb"
Ignoring debug-1.7.1 because its extensions are not built. Try: gem pristine debug --version 1.7.
Revert "Clear gem paths for each test"
This reverts commit 6698b580dd.
When a test worker hangs and timeouts, the test runner crashes with the
following stack trace:
ruby/tool/lib/test/unit.rb:1747:in `puke': undefined method `backtrace' for Timeout::Error:Class (NoMethodError)
from ruby/tool/lib/test/unit.rb:790:in `block in _run_parallel'
from ruby/tool/lib/test/unit.rb:788:in `each'
This commit adds handling for Timeout::Error and outputs a message.
* So deprecated methods/constants/functions are dealt with early,
instead of many tests breaking suddenly when removing a deprecated
method/constant/function.
* Follows https://bugs.ruby-lang.org/issues/17591
