According to Aileen Ward's biography of John Keats (English poet (1795-1821), who took an interest in English slang of the day, "hanging out" connoted "stopping at a tavern," i.e. spending time drinking, which fully comports with the modern sense of the slang expression. This indicates that the phrase was current in London in 1816 at the latest!
