Hopefully the first of many related to #11700. With these changes the railties tests wont 100% pass but at least they will run and show the errors. The first problem was the @method_name variable was never set. This was causing ENV["ISOLATION_TEST"] to always be nil which would cause the test output to never be written to the tempfile. The second problem was that an invalid -t option was being passed to minitest and minitest was erroring out. The third problem was the run method needs to always return an instance of the test class it is trying to isolate. We were returning a ProxyTestResult instead.
+ Namespace changes, overhaul of runners. + Internal ivar name changes - Removed a logger globally applied to tests that spew everywhere?!? + Override Minitest#__run to sort tests by name. + Reworked testing isolation to work with the new cleaner architecture. - Removed a bunch of tests that just test minitest straight up. I think these changes were all merged to minitest 4 a long time ago. - Minor report output differences.
MiniTest 4.7.3 detects the presence of SIGINFO and stores the answer in a constant. It seems that MiniTest 4.7.4 changes this, and instead relies on an info_signal method being implemented on the runner object. In ActiveSupport::Testing::Isolation, we use ProxyTestResult to stand in for the runner object. This object implements `method_missing`, and as such its #info_signal method has a truthy return value. This results in MiniTest trying to install the SIGINFO handler on platforms where SIGINFO does not exists. To fix, I am simply defining an explicit ProxyTestResult#info_signal method.
Minitest has changed to require this since seattlerb/minitest@728054b
…method_missing with Marshal.dump and Marshal.load is changing in ruby 2.0.0 later.
… warnings are in dependencies.

…e process. This allows for testing rails bootup (files are required, correct constants are set, etc...). Currently, this is implemented via forking only, but we will add support for jruby and windows shortly.
