Macros
#define	InputStreamInit(Size, Accumulate)
	Convenient wrapper around istream_init that casts Accumulate.
Calling a virtual member function

	Allocate a buffer and set the member function.
void	istream_close (istream_t *self)
	Free the buffer.
bool	istream_has_at_least (const istream_t *self, size_t count)
	Test if enough characters are available.
