Bug#947962: Current state of aerc dependencies

[Ben Fiedler <debian-packaging@services.bfiedler.ch>]

I took a look at the build dependencies, and it looks like the following
packages are missing in sid right now. I have grouped them by my own 
efforts:

Ongoing efforts by me:

* git.sr.ht/~sircmpwn/pty (fork of creack/pty, patch submitted upstream 
to switch back)
* github.com/ddevault/go-libvterm (ITP registered, package ready)

Dependencies to package:

* git.sr.ht/~sircmpwn/getopt
* github.com/emersion/go-imap
* github.com/emersion/go-imap-idle
* github.com/emersion/go-maildir
* github.com/emersion/go-message
* github.com/emersion/go-sasl
* github.com/emersion/go-smtp
* github.com/kyoh86/xdg
* github.com/miolini/datacounter
* github.com/riywo/loginshell

As far as I understand we will have to package all of these in order to 
build
aerc. I'd be glad for any help with any of these, otherwise I'll start 
packaging them
top-to-bottom when I have time.

Cheers,
Ben
