Summary:
Gdb servers like openocd may send many $O reply packets for the client to output during a qRcmd command sequence. Currently, lldb interprets the first O packet as an unexpected response. Besides generating no output, this causes lldb to get out of sync with future commands because it continues reading O packets from the first command as response to subsequent commands.
This patch handles any O packets during an qRcmd, treating the first non-O packet as the true response.
