dirname() is a slow function compared with __DIR__ and using
'/../'. Moodle has a large number of legacy files that are included
each time a page loads and is not able to use an autoloader as it is
functional code. This allows those required includes to perform as
best as possible in this situation.
This fixes an error where the RSS block config page would display
'Array' where the multiselect list of feeds should be when
accessed by a user who has not saved any RSS feed urls and yet the
block has been previously configured by another user.
PHP5 used to update error_reporting to 0 on functions called with the
suppress errors operator (@). In PHP7 it is not updated.

Based on a patch by Davo Smith of Synergy Learning
RSS feeds can fail, either permanently or temporarily.
After this patch if a feed fails it will not be tried again in the next cron run.
If it continues to fail the delay between tries will be increased.
When a feed succeeds it will go back to being fetched on each cron run.
This should make the CRON process for RSS feeds finish faster when
there are lots of invalid feeds.

Note: On purpose, the course format social wrong version (2015102100)
has been kept unmodified. Looking forward a solution right now.
If the <description> of the feed contains URLs longer than 30 characters, the
URL is split because of the break_up_long_words(). When combined with the
filter that converts URLs to links, this produces broken links.
The proper solution would be to improve break_up_long_words() so that it does
not modifies URLs at all. As a temporary solution for our purpose now is to
call format_text() prior to break_up_long_words() as it will not modify the
inner content of the <a> tag.
This should be fixed upstream. See also discussion at

Creates a shell rss_client.xml file, which contains no feeds. This makes it behave the same as restoring a Moodle 1.9 backup into a different 1.9 site - the block is created, its title is as per the original course, but it has no feeds selected (and none are added to the site's feed list).
