-    Fix a bug when getting a gzip header extra field with inflate().
-    
-    If the extra field was larger than the space the user provided with
-    inflateGetHeader(), and if multiple calls of inflate() delivered
-    the extra header data, then there could be a buffer overflow of the
-    provided space. This commit assures that provided space is not
-    exceeded.
