Use {0} initializer for all stack allocated char arrays

Browse Source 
Lots of places in the code were already using {0} to initialize stack char
arrays, but memset() was being used as well.  This commit removes all
unnecessary memset() calls against char arrays that are already initialized
via {0} (which sets all members to zero for such arrays).
