This commit:

* Adds save the world functionality to AIX.
	Mutated shared libraries are NOT saved on AIX yet.

* Reorganizes the save the world startup code in libdyninstAPI_RT.so

* Fixes a bug in dyninstAPI/src/sol_proc.C that caused dyninst to
	retrieve either the path or pwd from the ptrace info
	(whichever it saw first) and not the other one.

* Adds save the world functionality to Dyner
	Now use the command 'saveStart' to begin marking instrumentation to
	be saved back to the executable file (analogous to BPatch_thread::startSaveWorld()).
	Use 'save' to save the current version of the mutatee to a file (analogous to
	BPatch_thread::dumpPatchedImage(char*)).

* Adds code so that on attach, save the world data is only collected when
	BPatch_thread::startSaveWorld() is called

	reorganized RTmutatedBinary such that it
	just calls the necessary function from the
	file format specific file  (RTmutatedBinary_<FILEFORMAT>.c)

	added save the world functionality
	Now use the command 'saveStart' to begin marking instrumentation to
