Tracking issue for OsStr conversions

[alexcrichton]

This is a tracking issue for stabilizing the convert feature in the standard library, which is primarily associated with converting OsStr and OsString to byte or string types. Due to the length of discussions on #27390 and #27657 this will likely required an RFC to move forward (I hope to write one soon)

[alexcrichton]

I've posted an RFC for these stabilizations.

Given that the RFC failed, should these APIs be deprecated? There does not appear to be a path toward stabilization.

Nominating for deprecation in 1.6.

The libs team discussed this during triage today and the decision was to deprecate.
