CPP1113 — minor accessors of SystemException should use pass by value, minor should be uint32_t

For SystemException class on page 36 mentions

const int32_t& minor() const;
void minor(const int32_t&);

But this is a basic type which we pass by value. Also minor should be an uint32_t, the code should list

uint32_t minor() const;
void minor(uint32_t);

Also the CompletionStatus is returned by value, no need for a const, so change

const CompletionStatus completed() const;

to

CompletionStatus completed() const;

As last the constructor

explicit SystemException(int32_t minor, CompletionStatus status);

Should be

SystemException(uint32_t minor, CompletionStatus status);

SystemException updates

Proposed resolution is included in Issue #2 description
