Linking Directives

In either linking mode, package-specific directives must be passed
through to cmd/link. These are communicated by writing //go: directives in a
Go source file compiled by gc. The directives are copied into the .o
object file and then processed by the linker.

The directives are:

//go:cgo_import_dynamic <local> [<remote> ["<library>"]]

	AmzVersionID    = "x-amz-version-id"
	AmzDeleteMarker = "x-amz-delete-marker"

	// S3 object tagging
	AmzObjectTagging = "X-Amz-Tagging"
	AmzTagCount      = "x-amz-tagging-count"
	AmzTagDirective  = "X-Amz-Tagging-Directive"

	// S3 transition restore
	AmzRestore            = "x-amz-restore"
	AmzRestoreExpiryDays  = "X-Amz-Restore-Expiry-Days"
	AmzRestoreRequestDate = "X-Amz-Restore-Request-Date"

	// Storage class is special, it can be replaced regardless of the
	// metadata directive, if set should be preserved and replaced
	// to the destination metadata.
	sc := r.Header.Get(xhttp.AmzStorageClass)
	if sc == "" {
		sc = r.Form.Get(xhttp.AmzStorageClass)
	}

	// if x-amz-metadata-directive says REPLACE then
	// we extract metadata from the input headers.
