Enable netconsole features to be set at compilation time. Create two Kconfig options that allow users to set extended logs and release prepending features at compilation time. Right now, the user needs to pass command line parameters to netconsole, such as "+"/"r" to enable extended logs and version prepending features. With these two options, the user could set the default values for the features at compile time, and don't need to pass it in the command line to get them enabled, simplifying the command line.
