Exclude hidden pages (config["hidepages"]) from RSS feed (see https://www.dokuwiki.org/config:hidepages)

FS#2738, fix double encoding of html entities in RSS feeds (updates feed.php for changes to Diff class introduced in PR#179)

Before this change the last modification time was taken from metadata
and then the revision that was specified there was loaded from the
attic. Now revisions from attic are only loaded when the page has been
modified more recently and the date is normally the last modification
time of the page source. This was a problem when the most recent change
was an external edit, then an older revision was shown in the feed.

This fixes the problem that media items in the feed got the title of the
previous item when useheading was enabled as no metadata is loaded for
media entries and thus the previous metadata was used again. This also
fixes dates for media files.

this should avoid false positive matches on user content (which is
already escaped at this point)

can someone with better regex skills please revise this?

The function tpl_getFavicon() was doing more than its name was implying. Therefore the new tpl_getMediaFile() was introduced (which is doing nearly exactly the same) and tpl_getFavicon() was deprecated.
tpl_favicon() can still be used, though.

  * Do not emit E_NOTICEs
  * Introduce explicit feed mode default value »recent« instead of handling
    every unknown feed mode as recent changes mode. This means:
    - FEED_MODE_UNKNOWN is only executed if the given feed mode is indeed
      unknown. This is specifically not the case if no feed mode request param
      has been specified or the requested feed mode is »recent«.
    - FEED_MODE_UNKNOWN dies with an error as default behaviour
  * opt[items] is forced to be a non-negative integer
  * opt[show_minor] is forced to be a boolean and thus has a default value of
    false instead of null

As of VIM 7.3 it is no longer possible to specify the encoding in the
modeline. This gives an error message whenever such a file is opened,
thus this commit removes the enc setting from the modeline.

This patch introduces three new events, FEED_OPTS_POSTPROCESS, FEED_MODE_UNKNOWN and FEED_DATA_PROCESS that allow for action plugins to hook into every part of the feed creation process.

This patch moves all HTTP sending related functions to inc/httputils.php

Handling of range requests was rewritten completely to support mutirange
requests. This should fix problems with Adobe Reader but needs testing.

The use of realpath() to clean up relative file names caused some
trouble in certain setups relying on symlinks or having restricitve
file structure setups.

This patch replaces all realpath() calls with a PHP only replacement
which should solve those problems.

The feed now can export diff views (unified and HTML) as well as full HTML
page content.

Some things might be broken. Everybody please test it!

Instead of disabling the whole ACL feature when the auth backend is unavailable
just degrade the user to an anonymous user.
