  -----------
  [lldb] [Communication] Add a WriteAll() method that resumes writing

Add a Communication::WriteAll() that resumes Write() if the initial call
did not write all data.  Use it in GDBRemoteCommunication when sending
packets in order to fix handling partial writes (i.e. just resume/retry
them rather than erring out).  This fixes LLDB failures when writing
large packets to a pty.
