The test_includes test was failing if OPENSSL_CONF_INCLUDE happened to
be set in the user's environment. To ensure that no tests accidentally
use this or other enviroment variables from the user's environment we
automatically set them centrally for all tests.

The afalg engine was moved down from engines/afalg/ to engines/, but
the test wasn't changed accordingly.  This was undetected because the
test program didn't fail when it couldn't load the engine.

incorrect buffer was being sent to EVP_CipherFinal_ex when

We were kinda sorta using a mix of $disabled{"static-engine" and
$disabled{"dynamic-engine"} in Configure.  Let's avoid confusion,
choose one of them and stick to it.

They depend on this feature because they use the engine ossltest,
which is only available as a dynamic engine.

If the environment variable HARNESS_ACTIVE isn't defined or
HARNESS_VERBOSE is defined, it's probable that lots of output is
desired.

To be able to run tests when we've built in a directory other than
the source tree, the testing framework needs a few adjustments.

test/testlib/OpenSSL/Test.pm needs to know where it can find
shlib_wrap.sh, and a number of other tests need to be told a different
place to find engines than what they may be able to figure out on
their own.  Relying to $TOP is not enough, $SRCTOP and $BLDTOP can be
used as an alternative.

As part of this change, top_file and top_dir are removed and
srctop_file, bldtop_file, srctop_dir and bldtop_dir take their place.

Two tests are added: one is a simple version tolerance test; the second is
a test to ensure that OpenSSL operates correctly in the case of a zero
length extensions block. The latter was broken inadvertently (now fixed)
and it would have been helpful to have a test case for it.
