Use of pb namespace incompatible with protobuf 3.15.0

[ahesford]

The new protobuf 3.15.0 seems to add a new pb namespace alias that breaks compilation of clementine. Replacing the pb namespace with cpb allows clementine to compile. A sample patch is available at https://github.com/ahesford/void-packages/blob/protobuf/srcpkgs/clementine/patches/pb_namespace.patch

The patch applies cleanly to 1.4.0rc1 but I am not sure about the head of master.

Have you spotted 3.15 in the wild yet?

I bumped the Void Linux package to 3.15.0 this morning, so it's making its way to the wild now.
