v8.0.0

This is the first release of the v8 series of the builtin actors, which will be used by the upcoming Filecoin v16 network upgrade. The builtin-actors are a new set of Rust-based actors, intended to be run in the new Filecoin Virtual Machine: https://github.com/filecoin-project/ref-fvm. They are based on work done by the Forest team.

The most notable changes for users include:

• The replacement of synthetic code CIDs (eg. fil/7/storageminer) with actual content-addressed code CIDs (see below* for the full list).
• The introduction of gas metering, which charges gas for units of execution.

In addition to the work needed (FIPs 0030, 0031, and 0032) to make this code run in the FVM, this series of actors also includes the following changes:

• FIP-0027
• Bugfix for the ProveReplicaUpdates method
• New proofs version for SnarkPack

*The full list of actor code CIDs for v8.0.0 is:
