liblog: logd: Add android_lookupEventTag_len() Allows us to mitigate the impact of MAP_PRIVATE and copy on write by calling android_lookupEventTag_len instead of android_lookupEventTag, and delaying the copy on write impact to the later. We return a string length in a supplied location along with the string pointer with android_lookupEventTag_len(const EventTagMap* map, size_t* len, int tag). The string is not guaranteed to be nul terminated. Since android_lookupEventTag() called even once can cause the memory impact, we will mark it as deprecated, but we currently have no timeframe for removal since this is a very old interface. Add an API for __android_log_is_loggable_len() that accepts the non null terminated content and fixup callers that would gain because the length is known prior to the call either in the compiler or at runtime. Tackle transition to android_lookupEventTag_len() and fixup callers.
