Modifed lldb_private::Process to be able to handle connecting to a remote target that isn't running a process. This leaves lldb_private::Process in the eStateConnected state from which we can then do an attach or launch. Modified ProcessGDBRemote to be able to set stdin, stdout, stderr, working dir, disable ASLR and a few other settings down by using new GDB remote packets. This allows us to keep all of our current launch flags and settings intact and still be able to communicate them over to the remote GDB server. Previously these were being sent as arguments to the debugserver binary that we were spawning. Also modified ProcessGDBRemote to handle losing connection to the remote GDB server and always exit immediately. We do this by watching the lldb_private::Communication event bit for the read thread exiting in the ProcessGDBRemote async thread. Added support for many of the new 'Q' packets for setting stdin, stdout, stderr, working dir and disable ASLR to the GDBRemoteCommunication class for easy accesss. Modified debugserver for all of the new 'Q' packets and also made it so that debugserver always exists if it loses connection with the remote debugger. llvm-svn: 126444
