Introduce typed accesses for the error types of AVFoundation,
CloudKit, Contacts, and CoreLocation. While here, fix the API notes
for the Contacts framework, which had an embarrassingly-wrong file
name ;)
The Clang attribute allows one to state that a particular enumeration
type describes an error, and associates it with a particular domain
constant. However, due to lack of API notes support, this attribute
wasn't actually getting used. Instead, we had a number of explicit
extensions to enum types to make them conform to the _BridgedNSError
protocol explicitly.
Now that we have API notes, use them to make these enums into error
enums with the appropriate domain, so that the Clang importer will
synthesize the _BridgedNSError conformances. Then, remove all of the
explicit conformances---and with them, the overlays for 12 frameworks.
There is a small fix to more eagerly consider these conformances as
"used" if an expression is formed with the error enum as a value
type. This better ensures that the conformances will be available at
runtime when needed.
This cleanup is needed to implement SE-0112 (NSError bridging),
although it is useful by itself.
As a first step to allowing the build script to build *only*
static library versions of the stdlib, change `add_swift_library`
such that callers must pass in `SHARED`, `STATIC`, or `OBJECT_LIBRARY`.
Ideally, only these flags would be used to determine whether to
build shared, static, or object libraries, but that is not currently
the case -- `add_swift_library` also checks whether the library
`IS_STDLIB` before performing certain additional actions. This will be
cleaned up in a future commit.
At some point I want to propose a revised model for exports, but for now
just mark that support for '@exported' is still experimental and subject
to change. (Thanks, Max.)
-import-underlying-module deliberately avoids autolinking against that module,
since normally it's used when building the Swift half of a single binary.
For the overlays, however, that's not what we want, so add the underlying
framework explicitly.

Introduce a number of small overlays to bridge the NSError domains for
a number of frameworks into existing imported enums. This batch only
covers cases where there is an existing NS_ENUM describing the codes
for the domain, so we need only extend that enum to provide the
appropriate _BridgedNSError conformance.
This is the bulk of rdar://problem/20536610.
