Luiz Francisco Rodrigues da Silva df68c4b9b1 Add a setting to use active mode in FTPFeedStorage (#3829) 
Add a setting to use active mode in FTPFeedStorage

FTP servers can be configured in active and passive mode, by default
Python and Scrapy use passive mode and there was no way to use active.

This commit adds a setting FEED_STORAGE_FTP_ACTIVE to allow a feed
to be exported to a FTP server configured in active mode.

Victor Torres f4f2b1695c Fix a memory leak on the Media Pipeline (Files and Images) (#3813) 
We're storing exceptions captured by Twisted on the media pipeline
cache, but we're also using the defer.returnValue method with our
own methods decorated with @defer.inlineCallbacks.

The defer.returnValue method passes returned values forward by
throwing a defer._DefGen_Return exception, which in its turn
extends the BaseException class and is captured by Twisted.

This way, the latest exception stored in the Failure's object may
also have an HtmlResponse object in its __context__ attribute. As
the Response object also keeps track of the Request object that
has originated it, you could figure it out how many RAM we're
wasting here.

This could easily lead to a Memory Leak problem when running
spiders with Media Pipeline enabled and a particular Request set
that tends to raise a significant number of exceptions.

Example triggers:
- media requests with 404 status responses
- user land exceptins coming from custom middlewares
- etc.
