Stephan Bergmann 7ceee0f1ec Extend loplugin:redundantinline to catch inline functions w/o external linkage
...where "inline" (in its meaning of "this function can be defined in multiple
translation units") thus doesn't make much sense.  (As discussed in
compilerplugins/clang/redundantinline.cxx, exempt such "static inline" functions
in include files for now.)

All the rewriting has been done automatically by the plugin, except for one
instance in sw/source/ui/frmdlg/column.cxx that used to involve an #if), plus
some subsequent solenv/clang-format/reformat-formatted-files.
