bug#23680: 25.1.50; ibuffer: unmark all buffers without confirmation

[Tino Calancha <f92capac@gmail.com>]

It is a nuisance to be asked for confirmation whenever
an user wants to unmark all buffers.

I)
The patch follow same approach as Dired: introduce a new
command which unmark all buffers without confirmation.

II)
It is easier to remember if Ibuffer use the same bindings as
the Dired analog commands.  This patch rebind 'U' to the new
command introduced in I); for 'ibuffer-do-replace-regexp',
originally bound to 'U', prefers 'r'.
