rt: Convert timezone to utf-8 on Windows

Previously #9418 fixed utf-8 assertion issue by wcsftime,
but the function didn't work as expected: it follows the locale
set by setlocale(), not the system code page.
This patch fixes it by manual multibyte-to-unicode conversion.
Refactor TypeContents to be more scrutable. In particular, create coarser bits
than the current ones, which were very fine-grained.  Also, cleanly distinguish
when properties must be found in *owned* types vs *reachable* types.

Fixes #10157
Fixes #10278
Rename misleading contains_managed to owns_managed
Make TypeContents consider the type `T` to be reachable via `*T` pointers

Fixes #9509
Re-arranging some things in btree.rs to accommodate testing.

Fixes #10278.
Fixes for compilation to iOS:

- remove /usr/include from the include path since the iOS SDK provides the correct version
- `_NSGetEnviron()` is private and not available on iOS
- `.align` without an argument is not allowed with the Apple tools. 2^2 should be the default alignment
- ignore error messages for XCode < 5
- pass include path to libuv
