This change brings in lldb-gdbserver (llgs) specifically for Linux x86_64. (More architectures coming soon). Not every debugserver option is covered yet. Currently the lldb-gdbserver command line can start unattached, start attached to a pid (process-name attach not supported yet), or accept lldb attaching and launching a process or connecting by process id. The history of this large change can be found here: https://github.com/tfiala/lldb/tree/dev-tfiala-native-protocol-linux-x86_64 Until mid/late April, I was not sharing the work and continued to rebase it off of head (developed via id tfiala@google.com). I switched over to user todd.fiala@gmail.com in the middle, and once I went to github, I did merges rather than rebasing so I could share with others. llvm-svn: 212069
