dynamic_debug: update Documentation/*, Kconfig.debug
In dynamic-debug-howto.txt:
- add section: Debug Messages at Module Initialization Time
- update flags indicators in example outputs to include '='
- make flags descriptions tabular
- add item on '_' flag-char
- add dyndbg, boot-args examples
- rewrap some paragraphs with long lines
In Kconfig.debug, note that compiling with -DDEBUG enables all
pr_debug()s in that code.
In kernel-parameters.txt, add dyndbg and module.dyndbg items,
and deprecate ddebug_query.
