 * We have 8 debug levels, in (numerical) increasing order of verbosity.

 * appear (of course, iff global debug flag is ON and we match the Type and SubType).
 * Finer granularity debug levels are currently not in use, although the feature exists.
 *
 * Another way to say this:
 * All the debug prints currently have 'debug_level' set to DBG_LVL_ALL .
 * You can compile-time change that to any of the below, if you wish to. However, as of now, there's
 * no dynamic facility to have the userspace 'TestApp' set debug_level. Slated for future expansion.
