with "make install -j8" it happens very often that two or more make
instances are creating the same directory in parallel. As a result one
instace creates the directory and second mkdir fails because the
directory exists already (but it did not while testing for it earlier).

Using RSA_PKCS1_PADDING with RSA_private_decrypt is inherently unsafe.
The API requires writing output on success and touching the error queue
on error. Thus, although the padding check itself is constant-time as of
294d1e36c2, and the logic after the
decryption in the SSL code is constant-time as of
adb46dbc6d, the API boundary in the middle
still leaks whether the padding check succeeded, giving us our
much-loved Bleichenbacher padding oracle.
Instead, PKCS#1 padding must be handled by the caller which uses
RSA_NO_PADDING, in timing-sensitive code integrated with the
Bleichenbacher mitigation. Removing PKCS#1 padding in constant time is
actually much simpler when the expected length is a constant (and if
it's not a constant, avoiding a padding oracle seems unlikely), so just
do it inline.

We recalculate the location of the directories we keep track of.
However, we did so after having moved to the new directory already, so
the data we did the calculations from were possibly not quite correct.
This change moves the calculations to happen before moving to the new
directory.
This issue is sporadic, and possibly dependent on the platform.

This extends 'req' to take more than one DN component, and to take
them as full DN components and not just CN values. All other commands
are changed to pass "CN = $cn" instead of just a CN value.
This adds 'genpc', which differs from the other 'gen*' commands by not
calling 'req', and expect the result from 'req' to come through stdin.
Finally, test/certs/setup.sh gets the commands needed to generate a
few proxy certificates.

While travelling up the certificate chain, the internal
