* InstructionStepThroughState.java: Added, fixing #5260.
* InstructionStepState.java (handleUpdate): Added code to
check if the PC is inside a PLT section, and then defer work to
above State. Fixes #5260.
* TestStepping.java (testInstructionStepThroughSection): Added.
* SteppingEngine.java (stepOut): Now requires Frames instead of
DebugInfoFrames.
(stepOut): Added, taking a State parameter for use from State classes.

For instance, 42 void 43* print(char *what) { 44 while (*what != '\0') { 45 write(1, what, 1); (fhpd) step Task stopped at line 56 in file /home/mark/src/git/frysk-obj/frysk-core/../../frysk/frysk-core/frysk/pkglibdir/funit-hello.c (fhpd) where #0 0x08048455 in __i686.get_pc_thunk.bx () from /home/mark/src/git/frysk-obj/frysk-core/frysk/pkglibdir/funit-hello it should do something more sensible such as step through the plt, or step over the called library function. Note that there's an unwinder bug lurking here.
