diamondburned c6679dc52c State: Separate Store into smaller interfaces, Cabinet API
This commit refactors the Store interface in State into smaller
interfaces in package store. These interfaces are combined into one
structure called a "Cabinet". The default implementation of those
interfaces have been rewritten in package defaultstore, while the old
no-op implementation stays with the store package.

This commit also omitted several state handlers for user events, as it
is unclear what they are actually structured like.
