* Provide public access for some internal functions, to enable swift-corelibs-foundation
* Add access to TimeZone internals for swift-corelibs-foundation
* Fix default TimeZone for Linux
* Remove unneeded private entry point
* Do not use a recursive definition of description for String.Encoding
* Merge in some WASI changes and other Data fixes
* Add temporary initializer to the stub URL
* Remove Hashable conformance for CocoaError. This allows userInfo to be Any instead of AnyHashable
* Remove some protocols which depend on NSError from swift-foundation -- they will live in swift-corelibs-foundation
* Adjust the debug description of the GMT ICU calendar to be a little less implementation-specific
* Use an English-only description for string encodings, for compatibility with existing SCL-F clients
* Use a more compatible definition of a backstop value for Bundle
* Remove String._Encoding
Previously we added a new type `String._Encoding` for FoundationPreview to mirror Foundation framework's `String.Encoding` to work around Clang importer's ambiguous lookup issue. It turns out that the new type isn't needed for this workaround. Adding a typealias itself is sufficient.
* String.Encoding can conform to Hashable universally
