This bug collects the challenges and packages that need to be adapted for
OpenSSL 3.0.0 upgrade.

Major changes in 3.0.0:

* OpenSSL 3.0 is a major release and consequently any application
  that currently uses an older version of OpenSSL will at the 
  very least need to be recompiled in order to work with the new version.
* The OpenSSL versioning scheme has changed with the 3.0 release to format:
  MAJOR.MINOR.PATCH
  The patch level is indicated by the third number instead of a letter
* Providers and FIPS support
  Providers collect together and make available algorithm implementations.
* Use of the low level APIs have been deprecated.
* Some cryptographic algorithms that were available via the EVP APIs
  are now considered legacy and their use is strongly discouraged.
* Engines and "METHOD" APIs are deprecated and shall be transformed to
providers
