Release LevelDB 1.17v1.171.17

- Cleanup: delete unused IntSetToString

  It was added in http://cr/19491949 (and was referenced at the time).
  The last reference was removed in http://cr/19507363.

  This fixes warning/error with pre-release crosstoolv18:
    'std::string leveldb::{anonymous}::IntSetToString(const std::set<long unsigned int>&)' defined but not used [-Werror=unused-function]

- Added arm64 and and armv7s to IOS build as suggested on leveldb mailing list.

- Changed local variable type from int to size_t

  This eliminates compiler warning/error and resolves
