otDnsBrowseCallback

Pointer is called when a DNS response is received for a browse (service instance enumeration) query. Within this callback the user can use `otDnsBrowseResponseGet{Item}()` functions along with the @p aResponse pointer to get more info about the response. The @p aResponse pointer can only be used within this callback and after returning from this function it will not stay valid, so the user MUST NOT retain the @p aResponse pointer for later use. For the full list of possible values for @p aError, please see `otDnsAddressCallback()`.
