   * Buffer management
   * -----------------
   *
   * This code provides an API to generic memory buffer management.  All
   * operations are performed on a buf structure, which is kept opaque to the
   * API user in order to avoid corruption of the fields and make sure that only
   * the internals can modify the fields.
   *
   * The first step is to allocate a new buffer using the buf_alloc()
   * function, which returns a pointer to a new buffer.
