    cryptodev: remove /dev/crypto pseudo-device
    
    Remove the /dev/crypto pseudo-device. OpenBSD, which invented this API,
    did this step back in release 5.7 (2015).
    
    Note that this commit only removes the userland-facing /dev/crypto
    device while still keeping the in-kernel crypto(9) API as-is. The plan
    is to finally remove crypto(9) in a future commit.
    
    The only applications within DragonFly that ever made use of /dev/crypto
    were tcplay(8), cryptsetup(8) and cryptdisks(8) via libtcplay. But this
    dependency on /dev/crypto was dropped in commit
    ede102cd94449fe52fa9da25631d9f15af6d62ef as of April 21, 2025 in favor
    of doing the crypto operations directly in userland without any help
    from the kernel via /dev/crypto.
    
    Userland libraries or applications like OpenSSH and OpenSSL do not use
    /dev/crypto, mainly for performance reasons (and portability).
