This commit adds operator+= and operator+ overloads for adding gdb::unique_xmalloc_ptr<char> to a std::string. I could only find 3 places in GDB where this was useful right now, and these all make use of operator+=. I've also added a self test for gdb::unique_xmalloc_ptr<char>, which makes use of both operator+= and operator+, so they are both getting used/tested. There should be no user visible changes after this commit, except when running 'maint selftest', where the new self test is visible.
