Beschreibung

Description:

These are various places where we need to follow up to complete removal of C style strings in the header map.

  1. HeaderString::find(const char* str) can probably be eliminated entirely by converting call sites to use getStringView().find().
  2. StringUtil::atoull currently requires creation of some temporary std::string objects because it expects C strings, and also returns a C style string. Most call sites ignore the return value, so they can be converted to use absl::SimpleAtoi or a new StringUtil function that takes and returns string views.
  3. UuidUtils::uuidModBy() should be migrated to take absl::string_view
  4. Span::setOperation() should be migrated to take absl::string_view
