* generic/tclStringObj.c: Added protections from invalid memory
* generic/tclTestObj.c: accesses when we append (some part of) * tests/stringObj.test: a Tcl_Obj to itself. Added the appendself and appendself2 subcommands to the [teststringobj] testing command and added tests to the test suite. [Bug 2603158]
