Bug 1539104 - Add a way to detect supported storage connection operations. r=mak In retrospect, overloading `Connection::connectionReady` to mean "is ready _and_ supports this operation" wasn't a good idea. This commit reverts that change (cfd44c936a9b), and adds two new methods: * `Connection::operationSupported`, to check if a connection supports sync or async operations. This method is public. * `Connection::ensureOperationSupported`, that asserts or returns an error if the connection doesn't support an operation. This is private. `operationSupported` is used by callers like `Service::minimizeMemory` to detect if the connection supports sync operations, since both sync and async connections implement `mozIStorageConnection` now. Finally, some callers used `!mDBConn` to check if the connection was ready, while others used `connectionReady()`. This commit changes them to use the latter.
