Uses cqlprotodoc from cassandra-website to generate the versioned native protocol spec html pages.
Uses process-native-protocol-specs-in-docker.sh as a wrapper around this to also generate the native protocol spec adoc page that includes all the versions and makes each header navigable. This is executed as part of the existing `ant gen-asciidoc` and doc/Makefile.
patch by Olexandr Luzhniy; reviewed by Mick Semb Wever for CASSANDRA-19915
Pre-3.0 nodes serialize a full cellname in the paging state, but doing
so is wasteful for 3.0 nodes. We can't however guarantee to which nodes
a particular paging state will be sent so we need to have a backward
compatibility.
The patch preserve the pre-existing format for the paging state (thus
requiring more work for 3.0 nodes) for the native protocol v3, but
change to a more efficient (for 3.0) format for the protocol v4. It is
then documented that paging states shouldn't be used across protocol
versions.
