This reverts commit e21cbb4, as the switch to EVP routines requires a more careful design where we would need to have at least our wrapper routines return a status instead of issuing an error by themselves to let the caller do the error handling. The memory handling was also incorrect and could cause leaks in the backend if a failure happened, requiring most likely a callback to do the necessary cleanup as the only clean way to be able to allocate an EVP context requires the use of an allocation within OpenSSL. The potential rework of the wrappers also impacts the fallback implementation when not building with OpenSSL. Originally, prairiedog has reported a compilation failure, but after discussion with Tom Lane this needs a better design. Discussion: https://postgr.es/m/20200928073330.GC2316@paquier.xyz
