[issue3531] file read preallocs 'size' bytes which can cause memory problems

New submission from Andrew Dalke <[EMAIL PROTECTED]>: I wrote a buggy PNG parser which ended up doing several file.read(large value). It causes a MemoryError, which was strange because the file was only a few KB long. I tracked it down to the implementation of read(). When given a size hint
