RPMLint 2.3

This is a minor feature release with the following improvements:

• BashismsCheck speed was improved for files with equal content
• For python modules, undefined-non-weak-symbol and shared-library-without-dependency-information
  error are not reported any more
• binary-or-shlib-defines-rpath can resolve $ORIGIN variable part and resolves
  relative file paths
• no-binary error is reported for all packages now that are not architecture independent
• BuildDateCheck and BuildRootCheck checks were unified and utilize mmap for a faster
  file processing
• New option --ignore-unused-rpmlintrc can be used for skipping of unused-rpmlintrc-filter errors
• Time used for package extraction and decompression was added to time report (-t)
• Build dependency was fixed for zstd python package

I want to thank the following new contributors for their efforts in this release:
@lrupp, @tacerus, @kraptor and @aekoroglu.
