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.

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.
This patch contains the fowllowing hacks:
(1) Add "--timetable-data=FILE" option for test-all
This option enables to dump timeline event
contains worker, suite, and start/end time.
(2) remove TestJIT in test_jit_debug.rb on parallel test.
it is duplicated test.
(3) move test_jit.rb and test_jit_debug.rb at first
because these two tests are bottleneck of parallel tests.
On my environment, `make test-all TESTS=-j12` reduced the total time
190 seconds -> 140 seconds.
`(ulimit -n 30; make test-tool)` fails with unexplicit message:
"undefined method `write' for nil:NilClass" due to lack of stdout.
This change makes it explicit. [Bug #5577]

parallel test (`make test-all TESTS=-j8`) runs tests on specified
number of processes. However, some test checkers written in
`runner.rb` are not loaded. This fix enable these checkers on
parallel tests.
