Ruby accepts explicit nil for output buffer arguments and allocates a
new String in that case. Update signatures and stdlib tests to match.
Updated signatures:
* _Reader#read
* _ReaderPartial#readpartial
* IO#{pread,read_nonblock,readpartial,sysread}
* ARGF#{read,read_nonblock,readpartial}
* StringIO#{read,pread,read_nonblock,readpartial,sysread}
* Zlib::GzipReader#read,readpartial
* OpenSSL::Buffering#{read,read_nonblock,readpartial}
