Re: refactoring basebackup.c

Thanks Tushar for the testing.

I further worked on ZSTD and now have implemented client side
compression as well. Attached are the patches for both server-side and
client-side compression.

The patch 0001 is a server-side patch, and has not changed since the
last patch version - v10, but, just bumping the version number.

Patch 0002 is the client-side compression patch.

Regards,
Jeevan Ladhe
