Even when fixed to the US locale (and thus avoiding surprising behaviour in e.g. Turkish locale with "i" and "I") there are unexpected behaviours when upper and lower casing non-ASCII characters. For example it's sometimes not symmetric, e.g.: "ẞ".toLowerCase() -> "ß" "ß".toUpperCase() -> "SS" In all the ExoPlayer usages we are either dealing with known-ASCII strings (e.g. MIME types) or comparing against ASCII constant strings anyway, so it seems easier to just use Guava's ASCII-only class in these cases. Util.toUpperInvariant() is null-tolerant, while Ascii.toLowercase() is not. Most usages in this change are clearly non-null. The BandwidthMeter usages aren't annotated @Nullable, but the current code *would* work if countryCode was null in both cases. These methods will now throw NPE if they're passed null.

ExoPlayer HLS library module
Provides support for HTTP Live Streaming (HLS) content.
Adding a dependency to this module is all that's required to enable playback of
HLS MediaItems added to an ExoPlayer or SimpleExoPlayer in their default
configurations. Internally, DefaultMediaSourceFactory will automatically
detect the presence of the module and convert HLS MediaItems into
HlsMediaSource instances for playback.
Similarly, a DownloadManager in its default configuration will use
DefaultDownloaderFactory, which will automatically detect the presence of
the module and build HlsDownloader instances to download HLS content.
For advanced playback use cases, applications can build HlsMediaSource
instances and pass them directly to the player. For advanced download use cases,
HlsDownloader can be used directly.
