[PATCH v7 33/40] apply: add 'be_silent' variable to 'struct apply_state'

From
Christian Couder <christian.couder@gmail.com>

Message-ID
<20160613160942.1806-34-chriscool@tuxfamily.org>
In-Reply-To
<20160613160942.1806-1-chriscool@tuxfamily.org>

This variable should prevent anything to be printed on both stderr and stdout.

Let's not take care of stdout and apply_verbosely for now though, as that will be taken care of in following patches.
