Bug#906259: ITP: smartparens -- auto insertion, wrapping, and navigation of ()s, delimiters, and tags for Emacs

[Nicholas D Steeves]

Update: I am pursuing an NMU for #951973 (RC) and plan to also unblock this
bug by solving #921328 in the same upload.

Other than this, I'm waiting for confirmation from upstream about which
scala-mode variant is needed
