Check that the request matches the signature
* fix CRL tests to work
* regenerate certificates to be at least 2048 bit
(fixes buster and rhel8 in buildbot)
* update generate-ssl-cert.sh to generate crl files
* make all SSL tests to use certificates generated
in generate-ssl-cert.sh, remove unused certificates
and make sure that private ca key is not deleted at the end of
the procedure, so that we could generate additional certificates
any time without regenerating everything
Don't use a fixed buffer for X509_NAME_oneline() in the client.
Do as the server does - allocate it dynamically.
For a test - regenerate certificates to have the server cert with
a long subject.
Moved CERT files to where they are used, avoids conflict
between two make files trying to install the same CERTs
SSL/*.pem,
Move: SSL/*.pem -> mysql-test/std_data/
