ef901829c1 Introduce the posix-rename@openssh.com extension handling
Changes done in sftp_rename such that it will use
posix-rename@openssh.com extension if supported
and send a SSH_FXP_EXTENDED request. If the
extension is not supported a normal SSH_FXP_RENAME
request will be sent.

2539d72b7c Add support for PKCS#11 provider in OpenSSL 3.0
The engine API in OpenSSL 3.0 is deprecated so we are in the progress of working
on a PKCS#11 provider for OpenSSL. This commit introduces a conditional build
with the pkcs11-provider support (instead of engines) with all the changes
required for the provider to work with existing code and tests.

The CI modification is only temporary before we will have the real package in
Fedora or somewhere to use.

1eb3df5254 Get rid of the deprecated OpenSSL API
It turns out there is a way to get the uncompressed format from the low-level
API, which is not (yet?) deprecated so this removes all of the TODO's for ECDSA
keys and moves the EC_KEY structure in the high-level EVP_PKEY.
