PEL: Const accessors for Private/UserHeader

Change the combined non-const accessor/setter functions for the
PrivateHeader and UserHeader fields to the standard const accessors, and
have separate setters for the fields that need to be modified.

In addition, make the 'get PrivateHeader' and 'get UserHeader' functions
on the PEL class return a const reference.

This allows const enforcement on the PEL class, for things like:

void func(const PEL& pel)
{
    auto id = pel.privateHeader().id();
}
