- Handle symvers.xz in kabi.attr (#2209253).
- Fix indirect __crc_* sumbols parsing in find-provides.ksyms
  and find-requires.ksyms to avoid matching multiple sections
  producing bogus duplicate provides for kmods that have both __kcrctab
  and __kcrctab_gpl sections (#2115811, #2178935).
- Call "readelf -R" on a correct section in find-requires.ksyms.
- Rewrite section data extraction in find-provides.ksyms and find-requires.ksyms
  to avoid garbage at the end of extracted sections, causing unnecessary awk
  complaints (#2115811).
- Perform section parsing inside the awk script in find-provides.ksyms
  and find-requires.ksyms to avoid hitting command line argument limit
  when handling large .rodata sections (#2178935).
