Limit usable Buffer size without changing allocated size.

Browse Source 
Allow buffers to report a lower size than their allocated size. This means a larger buffer can be used to do the work of a smaller buffer without having to create a new buffer and concatenate.

This is useful for blocking I/O where the buffer may be too large for the amount of data that is available to read.
