Fixes #2413.

Fixes #2417.

clone() always returns a new object, which wasn’t being used in
this case. 

Some decoders will throw randomly, that doesn’t mean that we can’t 
continue on to try other decoders. 

Fixes #2406.

Fixes #2407

Group resource decoders into buckets, where the user can specify a bucket ordering so that prepending and appended is localized to the bucket.

It's pretty expensive to do, so we're wasting time for videos. If
setDataSource is called with a non-video, it will throw an exception
which in turn will cause us to move on to the next decoder, so the
behavior shouldn't change.

Fixes #2059

Progress towards #2354

Fixes #1510.

Fixes an issue where setting options on the generated GlideRequest after
having used it to load one image would throw an exception because the
internal RequestOptions object was locked when the first load was 
started. Now we apply autoClone() to make sure that the options object
for the first load isn’t modified by subsequent changes to options, but
also allowing those changes to occur.

Progress towards #2379.

It seems like this shouldn’t be necessary, but it fixes a PMD warning.

Fixes #2394.

The annotation can only be added to final methods, so we have to use
@SuppessWarnings for RequestOptions instead. As a result callers of
transforms() will have to suppress the warning on their end as well.

Fixes #2383.

Also fixes an issue where if we failed to find a support Fragment in
a FragmentActivity, we’d never check for a non-support Fragment in the
same Activity.

Fixes #2370.

floor is necessary to make sure that we populate all pixels in the
Bitmap, but it's not necessary to use to check if our input Bitmap has
already been transformed and can be returned as is. Using floor can
cause us to re-draw a Bitmap unnecessarily.

This allows models to handle equity for internal states that can be different from the target image result that is handled with equals()/hashCode()
For example to allow restart of image download from a new source but still using the same cache in Glide.

In addition to v3.0.1 being super old, it looks like earlier version(s)
of OkHttp have a race that will leak resources when requests are
enqueued instead of executed and cancel is called.

Progress towards #1996.

Fixes #1063.
