Problem (as stated by @joncinque at token-2022 #616)
The SPL token program has some heavy dependencies that most users of the crate don't care about. This causes dependency issues and long compilation times.
Also, the program uses Agave dependencies, which creates circular dependencies and makes it impossible to upgrade to SDK v3 without some complicated gymnastics.
Summary of changes
Everything needed by Agave is now split into the spl-token-interface crate. On-chain programs can also use this as an rlib.
