A useful checkpoint along the way to a complete implementation of the Swift3 overlay for libdispatch on non-Objective C platforms. The overlay code builds successfully and simple example programs using queues and timers work as expected. The basic approach is to wrap the C libdispatch objects in Swift objects and make the C dispatch APIs available internally via the CDispatch module. A few pieces (marked with FIXME) are ifdefed out to avoid compilation problems (will get back to them in later commits) or still need to be implemented (release on deinit). Although the installed libdispatch can be used in Swift programs via 'import Dispatch', the swiftc command for the client program currently needs to pass additional command line flags (to be fixed later). For example: swiftc -Xcc -fblocks -Xcc -D__DISPATCH_BUILDING_SWIFT_MODULE__=1 Forever.swift Signed-off-by: Daniel A. Steffen <dsteffen@apple.com>

Instead of using a special macro, check for __has_feature(modules) to activate including stdio.h in dispatch.h on Linux. Also, fix one place where OS_OBJECT_SWIFT_3 was used outside of an OS_OBJECT_USE_OBJC block (to prepare for SWIFT_SDK_OVERLAY_DISPATCH_EPOCH being defined by the clang importer on non-Darwin platforms).

If the main thread calls pthread_exit on Linux, the process becomes a zombie. Modify dispatch_main to avoid this by adding a pthread_key destructor that calls dispatch_sig_thread (effectively stalling pthread exit until the program really exits). This patch relies on the TSD destructors being called in order of creation, which is currently the case in glibc. Signed-off-by: Daniel A. Steffen <dsteffen@apple.com>

[Data] fix crash when creating iterator of empty DispatchData Signed-off-by: Daniel A. Steffen <dsteffen@apple.com>
Deallocation / reference counting support for DispatchData in the wrapping overlay consisting of two main pieces. First, since DispatchData is a struct and dispatch_data_t is a COpaquePointer, we need an intermediate class __DispatchData on which to perform the reference counting operations to enable the backing _dispatch_data_t to be deallocated when they are no longer reachable. I overlooked the mapping of _dispatch_data_t to OS_dispatch_data in Dispatch.apinotes in my initial pull request for the wrapping overlay and as a result all the dispatch_data_t instances were not being reference counted. Second, enable the DispatchData.Deallocator portion of the API. After some experimentation, found a way to have the desired API without getting a reference to _TMBO in the generated code. Left a FIXME because the current approach is sub-optimal in where it converts from Swift blocks to @convention(block) blocks. Signed-off-by: Daniel A. Steffen <dsteffen@apple.com>

Unsafe[Mutable]Pointer<Void> is replaced by Unsafe[Mutable]RawPointer. Migrating often means simply removing casts to/from UnsafePointer<UInt8> and working directly with UnsafeRawPointer instead. Unfortunately some API's, like NSData still want UnsafePointer<UInt8>, which requires "binding" memory to UInt8 before passing it to the API. Signed-off-by: Daniel A. Steffen <dsteffen@apple.com>
