std: Make logging safely implemented

This commit fixes the logging function to be safely implemented, as well as
forcibly requiring a task to be present to use logging macros. This is safely
implemented by transferring ownership of the logger from the task to the local
stack frame in order to perform the print. This means that if a logger does more
logging while logging a new one will be initialized and then will get
overwritten once the initial logging function returns.

Without a scheme such as this, it is possible to unsafely alias two loggers by
logging twice (unsafely borrows from the task twice).
