Since 0e987a1 (am, rebase: teach quiet option, 2009-06-16), git-am
supported the --quiet option, and when told to be quiet, would only
speak on failure. Re-implement this by introducing the say() function,
which works like fprintf_ln(), but would only write to the stream when
state->quiet is false.

Notes:
v5
* Removed GIT_QUIET environment variable, as it turns out
git-sh-setup.sh will reset it, which means the user's environment
cannot affect it.
