Bartosz Gentkowski ec24687ce4 DOXYGEN: Add doxygen groups to header files in the common folder
Adding @defgroup and @ingroup doxygen tags into all headers
in the common folder that contain doxygen blocks.

This improves the structure, readability, and findability
of information in the resulting output.

This commit targets purely structure and does not deal with
the content of the currently existing doxygen documentation.

* Debug channels should only affect the display of additional debug output, based on
* their state. That is if they are enabled, channel specific debug messages should
* be shown. If they are disabled on the other hand, those messages will be hidden.
*
* @see gDebugLevel.
*
* Note that we have debug* functions which depend both on the debug level set and
* specific debug channels. Those functions will only show output, when *both* criteria
* are satisfied.
*
* @param channel the channel flag (should be OR-able i.e. first one should be 1 then 2, 4, etc.)
* @param name the option name which is used in the debugger/on the command line to enable
* this special debug level (case will be ignored)
* @param description the description which shows up in the debugger
* @return true on success false on failure
