Templates: use C++11 default member initialization

The code is more readable and less error-prone (this patch caught a few
uninitialized members) when the members are initialized in the same
place where they are declared. In many cases, empty default destructors
can be entirely removed, and we get faster implicitly declared inline
default constructors defined by the compiler.
