		Package grpcutil provides a bunch of utility functions to be used across the
		gRPC codebase.
Package-Level Type Names (only one, which is unexported)

	/* sort exporteds by: alphabet | popularity */
	/* one unexported ... *//* one unexported: */
	 type mdExtraKey (struct)
Package-Level Functions (total 9, in which 7 are exported)

	 func ContentSubtype(contentType string) (string, bool)
		ContentSubtype returns the content-subtype for the given content-type.  The
		given content-type must be a valid content-type that starts with
		"application/grpc". A content-subtype will follow "application/grpc" after a
		"+" or ";". See
		https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md#requests for
		more details.

		If contentType is not a valid content-type for gRPC, the boolean
		will be false, otherwise true. If content-type == "application/grpc",
		"application/grpc+", or "application/grpc;", the boolean will be true,
		but no content-subtype will be returned.

		contentType is assumed to be lowercase already.

	 func ContentType(contentSubtype string) string
		ContentType builds full content type with the given sub-type.

		contentSubtype is assumed to be lowercase

	 func EncodeDuration(t time.Duration) string
		EncodeDuration encodes the duration to the format grpc-timeout header
		accepts.

		https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md#requests

	 func ExtraMetadata(ctx context.Context) (md metadata.MD, ok bool)
		ExtraMetadata returns the incoming metadata in ctx if it exists.  The
		returned MD should not be modified. Writing to it may cause races.
		Modification should be made to copies of the returned MD.

	 func ParseMethod(methodName string) (service, method string, _ error)
		ParseMethod splits service and method from the input. It expects format
		"/service/method".

	 func ParseTarget(target string) (ret resolver.Target)
		ParseTarget splits target into a resolver.Target struct containing scheme,
		authority and endpoint.

		If target is not a valid scheme://authority/endpoint, it returns {Endpoint:
		target}.

	 func WithExtraMetadata(ctx context.Context, md metadata.MD) context.Context
		WithExtraMetadata creates a new context with incoming md attached.

	/* 2 unexporteds ... *//* 2 unexporteds: */
	 func div(d, r time.Duration) int64
		div does integer division and round-up the result. Note that this is
		equivalent to (d+r-1)/r but has less chance to overflow.

	 func split2(s, sep string) (string, string, bool)
		split2 returns the values from strings.SplitN(s, sep, 2).
		If sep is not found, it returns ("", "", false) instead.


Package-Level Constants (total 2, neither is exported)

	/* 2 unexporteds ... *//* 2 unexporteds: */
	const baseContentType = "application/grpc"
	const maxTimeoutValue int64 = 99999999
