auto merge of #14323 : richo/rust/features/strbuf_to_string, r=huonw

Converts `StrBuf` to `String` throughout rustc and the standard library.

Tests all pass locally, but usual caveats about platforms that aren't OSX apply since I don't have a test environment handy.

@alexcritchon mentioned that @pcwalton may have a patch incoming that should block this?

closes #14312
