[PATCH 04/16] dyndbg: rename __verbose section to __dyndbg

[Jim Cromie]

dyndbg populates its callsite info into __verbose section, change that
to a more specific and descriptive name, __dyndbg.

Also, per checkpatch:
  move extern struct _ddebug __(start|stop)__dyndbg[] to header file
  simplify __attribute(..) to __section(__dyndbg) declaration.
