Subteam report: libs 2016-01-22

Highlights

This week we made a number of decisions on outstanding libs PRs and github issues, which have been logged on their respective threads. RFC-wise, we've been moving a bit slowly, but we hope to make more progress on RFC shepherding now that the backlog has been cleared.

Next week we will determine the unstable APIs to put into FCP for stabilization/deprecation in Rust 1.8. Please have a look at the list and leave comments on any APIs you think we should consider.
