Updated libconfig to version 1.5

- Based on https://github.com/hyperrealm/libconfig/releases/tag/v1.5
  f9f23d7a95608936ea7d839731dbd56f1667b7ed
- Improvements that come with this libconfig version:
  * Don't fclose() a null pointer.
  * check if file being opened is a directory
  * added config_set_options(), config_get_options(), setOptions(),
    getOptions().
  * renamed config_setting_lookup_from() to config_setting_lookup() and
    documented it
  * floating point precision loss patch
  * scanner code cleanup
  * parser code cleanup
  * bugfix; capture root filename
- Parser generated with Bison 2.7
- Scanner generated with flex 2.6
- This includes the windows-compatibility commit
  909b06c07e30e456cc63f58d31b0e2f3aad4cc43 from upstream (although not
  part of version 1.5)
