init the name to 0

There are a few conditions where coverity finds a use of an uninitialized
field of the name_t struct. These are rather messy combinations of conditions,
so let's go with the simple solution here and just init everything to 0.
This may still have side-effects but at least they'll be more obvious than the
previous "use whatever memory is leftover from breakfast".

This patch also adds a missing init_name(), much for the same reason.
