Ryan Libby 3e5e9939cd ddb: enable the use of ^C and ^S/^Q ... This lets one interrupt DDB's output, which is useful if paging is disabled and the output device is slow. This follows a previous implementation in svn r311952 / git 5fddef7999 which was reverted because it broke DDB type-ahead. Now, try this again, but with a 512-byte type-ahead buffer. While there is buffer space, control input is handled and non-control input is buffered. When the buffer is exhausted, the default is to print a warning and drop further non-control input in order to continue handling control input. sysctl debug.ddb.prioritize_control_input can be set to 0 to instead preserve all input but lose immediate handling of control input. This could for example effect pasting of a large script into the ddb console.
