Added the new way we will eventually do all attaches and launches. First clients
will fill out either a SBLaunchInfo or SBAttachInfo class, then call: SBProcess SBTarget::Launch (SBLaunchInfo &, SBError &); SBProcess SBTarget::Attach (SBAttachInfo &, SBError &); The attach is working right now and allows the ability to set many filters such as the parent process ID, the user/group ID, the effective user/group ID, and much more. The launch is not yet working, but I will get this working soon. By changing our launch and attach calls to take an object, it allows us to add more capabilities to launching and attaching without having to have launch and attach functions that take more and more arguments. Once this is all working we will deprecated the older launch and attach fucntions and eventually remove them. llvm-svn: 151344
