Add support for zstd base backup compression.

Browse Source 
Both client-side compression and server-side compression are now
supported for zstd. In addition, a backup compressed by the server
using zstd can now be decompressed by the client in order to
accommodate the use of -Fp.

Jeevan Ladhe, with some edits by me.
