Add completion styling
Readline has a styling feature for completion -- if it is enabled, the
common prefix of completions will be displayed in a different style.
This doesn't work in gdb, because gdb implements its own completer.
This patch implements the feature. However, it doesn't directly use
the Readline feature, because gdb can do a bit better: it can let the
user control the styling using the existing mechanisms.
This version incorporates an Emacs idea, via Eli: style the prefix,
the "difference character", and the suffix differently.
