This eliminates duplicate identifier computations. The new implementation also significantly reduces allocations while computing identifier for a large dependency tree.

This imposes a hard upper limit to concurrency during dependency satisfaction and moves all dependency-related code out of individual implementations of Artifact. This change also includes ctx and msg as part of Cache.

Only write should be cleared here, clearing execute causes execArtifact to be unable to start anything since no Artifact is able to produce an executable file.

This allows for more flexibility during implementation. The use case that required this was for expanding single directory tarballs.

The previous implementation exposes arbitrary user input to the cache as an identifier, which is highly error-prone and can cause the cache to enter an inconsistent state if the user is not careful. This change replaces the implementation to compute identifier late, using url string as params.

This moves all cache I/O code to Cache. Artifact now only contains methods for constructing their actual contents.
