A few very minor library issues

[Kevin Bourrillion]

Just a few little things.

1. I feel the Stream methods findFirst() and findAny() can really be named
just first() and any().  The "find" is just odd and doesn't do enough.
Failing that, I'd go for firstElement() / anyElement().

2. I like Stream.substream(), but Stream.sub*S*tream() is undeniably
consistent with the collections API (subSet, etc.; sure, String.substring()
doesn't follow that, but it's "farther away"). I'm actually on the fence
here, because I think "substream" is strictly the *correct* way to
camel-case the word "substream"...

3. Are we concerned that the name Map.computeIfAbsent() obscures what the
mutative effect on the map is?
