ibaker c50084e7ba Replace Util.toLowerInvariant() with Ascii.toLowerCase()

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.

This change also includes some null-twiddling, because
Util.toLowerInvariant() is null tolerant, while Ascii.toLowerCase() is
not. Most of the usages were already non-null, and it was easy enough to
change the remaining ones to be so by simple reordering of statements.

I'll make an equivalent change for Util.toUpperInvariant() next.

ExoPlayer DASH library module

Provides support for Dynamic Adaptive Streaming over HTTP (DASH) content.

Adding a dependency to this module is all that's required to enable playback of DASH MediaItems added to an ExoPlayer or SimpleExoPlayer in their default configurations. Internally, DefaultMediaSourceFactory will automatically detect the presence of the module and convert DASH MediaItems into DashMediaSource instances for playback.

Similarly, a DownloadManager in its default configuration will use DefaultDownloaderFactory, which will automatically detect the presence of the module and build DashDownloader instances to download DASH content.

For advanced playback use cases, applications can build DashMediaSource instances and pass them directly to the player. For advanced download use cases, DashDownloader can be used directly.
