Summary
-------

In AMI's parser, when it receives a long line (> 1024 characters), it discards that line, but continues to process the message normally.

Typically, this is not a problem because a) who has lines that long and b) usually a discarded line results in an invalid message. But if that line is specifying an optional field, then the message will be processed, you get a 'Response: Success', but things don't work the way you expected them to.

This patch changes the behavior when a long-too-long parse error occurs.
* Changes the log message to avoid way-too-long (and truncated anyways) log messages
* Adds a 'parsing' status flag to Response: Success
* Sets parsing = MESSAGE_LINE_TOO_LONG if, well, a line is too long
* Responds with an appropriate error if parsing != MESSAGE_OKAY


This addresses bug AST-961.

Testing
-------

Used netcat to send commands with AMI, verifying that commands with long lines were rejected, and commands without long lines received after that were accepted.


Thanks,

David
