Port XGZIP and zlibNX to IBM i

With Power9 compatibility mode enabled we could improve compression and file transfers using SSH or SFTP.
Traditionally SSH compression on IBM i is not lightning fast, and this could help improve file transfer times.
I guess 5733ICC can improve pre-compression times.

Use Case:

We could use zlibNX with SFTP or xGZIP with SSH piping to transfer files using hardware acceleration.

    So... if we use those tools... can we have a hardware enhanced gzip/pigz/SAV* commands version?

    There may be support added in ILE-available interfaces, but there is no feasible way to implement this fully in PASE. We support other compression tools such as xz, bzip2, and zstd which offer various tradeoffs in compression speed vs size that may be more appropriate.

    I think this might already exist under AIX and should be able to install it directly to the PASE environment.™-nx-gzip-accelerator-aix
