Prior to the 2.20 release, the function was just changed to fail
unconditionally, in commit a1a6a401ab.
This commit removes the function completely, including gconv bits
which depend on it.
This changes the gconv ABI, which is not a public interface.
The cached offset is reliable to use in ftell when the stream handle
is active. We can consider a stream as being active when there is
unflushed data. However, even in this case, we can use the cached
offset only when the stream is not being written to in a+ mode,
because this case may have unflushed data and a stale offset; the
previous read could have sent it off somewhere other than the end of
the file.
There were a couple of adjustments necessary to get this to work.
Firstly, fdopen now ceases to use _IO_attach_fd because it sets the
offset cache to the current file position. This is not correct
because there could be changes to the file descriptor before the
stream handle is activated, which would not get reflected.
A similar offset caching action is done in _IO_fwide, claiming that
wide streams have 'problems' with the file offsets. There don't seem
to be any obvious problems with not having the offset cache available,
other than that it will have to be queried in a subsequent
read/write/seek. I have removed this as well.
