Removed. (stream_write): Keep looping (non-blocking case) if errno is

2001-10-29  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-tcp-stream-openssl.c (my_SSL_write): Removed.
	(stream_write): Keep looping (non-blocking case) if errno is
	EAGAIN, EINTR or EWOULDBLOCK. For NONBLOCKing I/O, sync up with
	CamelTcpStreamRaw. As with CamelTcpStreamRaw/SSL - make sure to
	write out everything before returning.
	(my_SSL_read): Removed.
	(stream_read): Just call ssl_error_to_errno() and check the errno
	values that we care about so we can keep the general look of all
	this stream code the same. Also when checking the return value of
	SSL_read, check for <0 instead of ==-1 since the man page for
	SSL_read doesn't say it will return -1 on fail, it just says <0.
	(stream_flush): Don't fsync() since syncing on a socket is a Bad
	Thing (tm).

	* camel-tcp-stream-ssl.c (stream_write): Make sure we write out
	everything just like in camel-tcp-stream-raw.c.

	* camel-stream-buffer.c (camel_stream_buffer_gets): If
	camel_stream_read() returns -1, don't necessarily return -1 to our
	caller since it's possible that we did actually "read" some data
	(ie, we copied some pre-buffered data into the out buffer).

	* camel-stream-buffer.h: Removed CAMEL_STREAM_BUFFER_NEWLINE since
	it never got used anywhere and it isn't supported anyway.
