gcc8 and Wstringop-truncation

Browse Source 
gcc8 introduced a new warning (Wstringop-truncation) which in our case
is being treated as error.
Disabling the warning globally might introduce bugs related to string
truncation which are not desired by the developer (e.g. bug).
Instead, this patch disables the warning only for those occurences
which have been verified to be non-bugs but the desired behaviour as per
developer will.
