[FL-2415] Storage: blocking file open (#1078)

* Storage: correct replacement for "/any" path in path holder
* Unit tests: storage, blocking file open test
* File stream: error getter
* Storage: common copy and common remove now executes in external thread
* Filesystems: got rid of unused functions
* Storage: untangle dependencies, ram-frendly filesystem api
* iButton: context assertions
* Storage: pubsub messages
* Storage: wait for the file to close if it was open
* Storage: fix folder copying
* Storage: unit test
* Storage: pubsub documentation
* Fix merge error
* Fix memleak in storage test
* Storage: remove unused define
