Subteam report: libs 2015-10-31

Highlights

From last week, we had two RFCs in FCP:

• FCP PR #1291 RFC: Promote the libc crate from the nursery -- merged, now available in the main repository, and a version bump will be coming soon!
• FCP PR #1307 Add some additional utility methods to OsString and OsStr - merged, and tracking issue

Two new RFCs were moved into FCP this week as well:

• FCP PR #1270 RFC: #[deprecated] for Everyone
• FCP PR #1288 Improvements to the Time APIs

As a reminder, this coming week is where we'll decide on the set of FCP issues for APIs in the standard library to stabilize during the 1.6 cycle. If you've got an API you'd like to see stable, please feel free to comment on the list of issues.
