Remove System.Slices

[ahsonkhan]

@KrzysztofCwalina, can you provide more details/context?

[KrzysztofCwalina]

I think OwnedMemory, Memory, ReadableBuffer/ReadOnlyBytes should ship in a package called something like System.Buffers.<something>, maybe System.Buffers.Primitives.

At that point, why do we still need System.Slices? What other APIs are there that won't be either in System.Memory or in System.Buffers.?

System.Buffers., maybe System.Buffers.Primitives.

I would vote for System.Buffers.

[KrzysztofCwalina]

The problem with System.Buffers is that it already exists in corefx. We probably don't have enough bake in time to put these types there.

[jkotas]

I see ... so should be just some temporary name that does not really matter then?

[aL3891]

I like System.Memory[.]Primitives because it feels like "memory" is a more generic concept than "buffer".

Slices is gone with #1319. There is a couple pieces of span extension cleanup being done as part of a different work item.
