Use memoryview instead of buffer

kevin-brown · kevin-brown · commit 01e40b5e02e9 · 2014-07-13T17:29:58.000-04:00
This uses memoryview by default, which is supported in Python 3
and Python 2.7, but not Python 2.6, and falls back to the old
`buffer` type in Python 2.6 and when the memoryview does not
support the type, such as when mmap instaces are passed in.
