Subject: [PATCH] Use imported soft-pkcs11 for tests
Update the soft-pkcs11 code for OpenSSL 1.1, fix some warnings,
integrate it into the build system, and use it for the PKINIT tests.
(cherry picked from commit e5ef7b69765353ea62ad8712a229ed4e90a8fe17)
(cherry picked from commit 47e66724b9d5cfef84965d99c83d29e4739932e3)
