Summary: Added clearerr() to clear EOF state

Initial Comment:
This patch is to fix bug 1523853.
Now file.read() works as written in the doc, which says
"An empty string is returned when EOF is encountered immediately."
Before this fix, An empty string was returned even when the last
read() encountered EOF.

I was not able to reproduce the problem.  I tried to read through the end
of the file, append to the file from an external process and read again. 
It worked as expected: more data was read.

The proposed patch seems to be redundant: once ferror(f->f_fp) is known to
be 0, clearerr will do nothing and in the alternative branch clearerr is
already there.
