cmd/cgo: special case C ptr types to use uintptr Some C types are declared as pointers, but C code stores non-pointers in them. When the Go garbage collector sees such a pointer, it gets unhappy. Instead, for these types represent them on the Go side with uintptr. We need this change to handle Apple's CoreFoundation CF*Ref types. Users of these types might need to update their code like we do in root_cgo_darwin.go. The only change that is required under normal circumstances is converting some nils to 0. A go fix module is provided to help.
