- Fix the build on Clear Linux, coping with redundant declarations of
   function prototypes in python3 header files by adding
   -Wno-redundant-decls to build with PYTHON=python3 (Arnaldo Carvalho de Melo)
 
 - Fixes for processing inline frames in backtraces using DWARF based
   unwinding (Milian Wolff)
 
 - Cope with bad DWARF info for function names for inline frames,not
   trying to demangle this symbol. Problem reported with rust but
   reproduced as well with C++. Problem reported to the libbpf
   maintainers (Milian Wolff)
 
 - Fix python export to postgresql and sqlite code (Adrian Hunter)
