[swift-corelibs-dev] [swift-corelibs-libdispatch] Port transform and use libbsd (#13)

[Pierre Habouzit]

First we can't use HAVE_MACH which isn't namespaces in a system header. Second we don't want to ship configure.h either anyway.

Last we discussed with Daniel about that already and we'll probably end up having things based on __have_include() eventually. So for now __APPLE__ will do in headers. Everywhere else HAVE_MACH is used correctly as expected.
