Most of the time, the issues we want to debug with the firmware dump mechanism are transient. It is then very hard to stop the recording on time and get meaningful data. In order to solve this, I add here an infrastucture of triggers. The user will supply a list of triggers that will start / stop the recording. We have two types of triggers: start and stop. Start triggers can start a specific configuration. The stop triggers will be able to kick the collection of the data with the currently running configuration. These triggers are given to the driver by the .ucode file - just like the configuration. In the next patches, I'll add triggers in the code.
