cwr_next():  move invariants out of loops.

This simplifies and clarifies the code, and gives a small speedup.

If bots fail due to using this flag, the buildbot scripts have to be modified
to omit it. Regrtest ignores it anyway.

Moving subprocess execution of tests into a function.

Modern processors tend to make consecutive memory accesses cheaper than
random probes into memory.

Small sets can fit into L1 cache, so they get less benefit.  But they do
come out ahead because the consecutive probes don't probe the same key
more than once and because the randomization step occurs less frequently
(or not at all).

For the open addressing step, putting the perturb shift before the index
calculation gets the upper bits into play sooner.

This kine was already replaced by
Lib/test/test_email/data/msg_26.txt = BIN
which is just below the last line in the patch context.

Fix issue 18889: test_sax: multiple failures on Windows desktop.

"The fix" is to tell Mercurial that the test files are binary.

Windows developers:  to get the correct line endings in your checkout,
delete Lib\test\xmltestdata, and then "hg revert" that directory.

Why the Windows buildbots didn't fail test_sax remains a mystery :-(

Merge test/subprocessdata/inherited.py into test/subprocessdata/fd_status.py

Unclear to me why it was pushed to begin with.  See issue 11798.
Perhaps it's because regrtest with -R was failing?  Fine, but
that's better than regrtest _always_ failing ;-)

[issue #18730]

Closes #18720.

Patch import and initialization in SearchEngine to make testing easier.
Improve docstrings, especially to clarify the double role of 'ok' parameters.
