Valgrind friendly openssl, if getenv("CFENGINE_TEST_PURIFY_OPENSSL")

Even if you compile your openssl with -DPURIFY and no-asm, valgrind
still outputs a very long list of uninitialised variable warnings. It
turns out that the "blinding" feature of openssl is the culprit.

Fix package_list_update_ifelapsed having no effect on "apt-get update"

Redmine #3981, #5339.

It is documented as having the described effect, but does not.

The timestamp for the last update is now maintained by a timestamp
file, /var/cfengine/state/software_update_timestamp_<manager>, where
<manager> is the package executable that is being used for the current
promise.
Ideally it should be integrated with the database, but we want the low
risk solution right now, and we plan to replace this code anyway.

Removing buggy undocumented feature ...

... according to discussion at
https://github.com/jimis/core/commit/d4999f291bf937ef36ee05c28149ca773b172865
Fix selectservers().

See Redmine #5458. Thanks to Bob Ingersoll for spotting it.
Add acceptance test for selectservers().
TryConnect() should return error when select() times out.
Logging in milliseconds is ugly.
Fix socket descriptor leak.
Acceptance test for selectservers() now checks failures as well as successes.

Unfortunately some requests may timeout, which means that the test will
take 30s to complete. In the future we should enable parallel test
harness to avoid waiting.
Selectservers() now logs INFO in case of timeout.
Beautify message.
Use dcs_passif_expected() to check and report all classes are set.
Change timeout so that acceptance test takes only 5 seconds instead of 30.

Does not work for now, should work after redmine #5497 gets fixed.
Merge branch 'jimis/selectservers' into 3.6.x

Leak-fix in FnCallRegExtract().

One of its premature returns neglected to free the arrayname.

Report repaired compliance for promise types that use methods.

Services promises call VerifyMethod and would never be reported as
repaired, as VerifyMethod filters that result out (the promise inside
the method is still reported as repaired). Instead, filter the
compliance in the existing helper function that is called only by the
evaluator.

Fixes #5504
