jas_stream_close closes a file object it didn't open

[giraffedata]

When I open a stream from an existing open file with jas_stream_fdopen(), then when I close that stream with jas_stream_close(), it should leave that file open.

In older libjasper, there was code in jas_stream_fdopen() to set the flag JAS_STREAM_NOCLOSE and code in jas_stream_close() to forego closing if that flag was set.

Current libjasper sets flag JAS_STREAM_FILEOBJ_NOCLOSE, but jas_stream_close() pays no attention to it and in practice, the file gets closed. I see no place that JAS_STREAM_FILEOBJ_NOCLOSE .

@giraffedata Just out of curiosity, in which version of JasPer did this previously work? It seems to have been broken for a while. In any case, I have added a check for this flag to the code. Please confirm that it now works for you. The fix is in commit 66f3d9d.

The version in which I see it work is 1.600.0. I'll pass this along to the person who reported the problem to me.

@giraffedata Thanks for the clarification. The 1.600.0 version is very old. In any case, the problem should be fixed now, I think.
