* content: added GetCompressionHeaderID and GetEncryptionKeyID to content.info Both must be zero in index v1 but will be non-zero in index v2 to support in-content compression and key rotation in the future. * content: cleaned up index v1 code * content: added index v2 implementation * content: updated index test to verify that we're able to store all supported values in all Info fields * content: optimized sorting of content.Info by content ID using bucket sort and parallelization For 10M contents this reduces sort time from 10s to ~2s * content: fixed a bunch of off-by-one errors in index v2, added tests * content: fixed test failures due to increased validation * content: plumbed through index version (currently hardcoded to v1) in content manager
