[bug#37444] [PATCH] added aerc, a simple email client and its dependcies

[Ricardo Wurmus]

Hi Martin,

> This adds aerc, which is a terminal based email client written in go. 

Thank you for your patch!

Could you please separate the independent changes into separate commits
and add commit summaries?  For example, the update of
go-github-com-mitchellh-go-homedir should be done separately.

Please also explain why “inputs” had to be changed to
“propagated-inputs” in some packages, and mention these kind of changes
in the commit summary.

Thanks!
