Reads large blocks in a safe way. Unlike fp.read(n), this function
doesn't trust the user. If the requested size is larger than
SAFEBLOCK, the file is read block by block.
:param fp: File handle. Must implement a <b>read</b> method.
:param size: Number of bytes to read.
:returns: A string containing <i>size</i> bytes of data.
Raises an OSError if the file is truncated and the read cannot be completed
