avoid creating expensive stacktrace in dbg_deprecated()

now the method is aborting early again unless the data is actually used

introduce INFO_DEPRECATION_LOG event

This adds an event to dbg_deprecated(). This allows plugins to handle
deprecation warnings. One example would be @cosmocode/dokuwiki-plugin-sentry

One thing I don't like, but don't know how to avaoid is that this
function used to abort super early when $conf['allowdebug'] wasn't set.

However for the sentry plugin you probably would want logs, but still do
not show any debugging to end users (which allow debug would do).

So now the backtrace is always built, the event triggered and then
everything is sent to dbglog() which may simply throw everything away.

Suggestions on how to improve this welcome.

line lengths shortened

This makes sure all files use line lenghts shorter than 120 characters.

This is a quick fix. It might not always be the nicest change.

remove DOKU_INC checks

There is no need for this check, since these files should not have any
main code that is executed on direct call.

Update check supports HTTPS

If SSL is not supported, a HTTP request will be made. In the log the request type will be indicated, but on the frontend no additional message would be shown (I think it's better to notify admins about non-SSL situations, but currently when this fetch encounter error, no error message will be shown, so it's better not to add any warning).

Check the server has a sensible time

DokuWiki assumes that the server's time is correct. Especially page
revisions and cache handling depend on correct time. If that's not the
case it can lead to problems later (as mentioned in #1644).

This patch adds a very simple time check using the Date response header
from the DokuWiki server to our do=check mechanism.

Remove error supression for file_exists()

In an older version of PHP a file_exists() call would issue a warning
when the file did not exist. This was fixed in later PHP releases. Since
we require PHP 5.3 now, there's no need to supress any error here
anymore. This might even give a minor performance boost.

Fix for update messages never completely going away

The existing logic for messages.txt requires some valid update
response (ending in %) to the messages update check before it clears
the current messages.

However update.dokuwiki.org appears to return an empty string response
if everything is up to date. (ie http://update.dokuwiki.org/check/46.1 )

As a result if there are update messages in messages.txt they don't
automatically go away after updating to the current version. The only
time they change is when a newer release comes out. The upgrade plugin
has logic in it to force a re-download of messages.txt, but currently
this just re-downloads the old update messages.

This change explicitly allows for "" as a valid "no messages"
indicator (distinct from false, which is the HTTP error indicator.)
