Subject: [PATCH] perf annotate: Toggle full address <-> offset display

Handle 'f' key to toggle the display offset and full address.  Obviously
it only works when users set to see disassembler output ('o' key).  It'd
be useful when users want to see the full virtual address in the TUI
annotate browser.
