[PATCH v14 34/41] apply: don't print on stdout in verbosity_silent mode

When apply_verbosity is set to verbosity_silent nothing should be
printed on both stderr and stdout.

To avoid printing on stdout, we can just skip calling the following
functions:

	- stat_patch_list(),
	- numstat_patch_list(),
	- summary_patch_list().

It is safe to do that because the above functions have no side
effects other than printing:

- stat_patch_list() only computes some local values and then call
show_stats() and print_stat_summary(), those two functions only
compute local values and call printing functions,
- numstat_patch_list() also only computes local values and calls
printing functions,
- summary_patch_list() calls show_file_mode_name(), printf(),
show_rename_copy(), show_mode_change() that are only printing.
