Change subject: core/linuxlist.h: fix and unify Doxygen documentation
......................................................................
core/linuxlist.h: fix and unify Doxygen documentation
- drop incorrect \ref and \a references;
- add missing documentation to LLIST_HEAD_INIT;
- document parameter 'member' of llist_entry();
- turn @argument naming into a valid \param format;
- fix 'type *' vs llist_head loop counter confusion;
- Capitalize and dot-terminate all sentences.
