…tiple constraints This fixes a problem with the new protobuf marshaling with the standard library. LLB digests are now forced into deterministic marshaling to ensure they produce the same digest when marshaled multiple times. In addition, the marshal cache has also been fixed to work in multi-threaded frontends with multiple different constraints. Previously, if an LLB vertex was used in multiple goroutines and marshaled concurrently, the cache would be broken. This could cause certain problems when a specific node was used multiple times in the same LLB tree. Signed-off-by: Jonathan A. Sternberg <jonathan.sternberg@docker.com>
