This now gives proper files and line numbers for errors

This makes it possible to safely overwrite ini replacements from within
any less file

still needs testing

When debugging is enabled (allowdebug enabled) JS errors are now catched
for each non-core JS file and logged with the additional information
from which file they came. This should make it easier to find out which
plugin is the cause for broken JS code. The feature isn't enabled by
default as defining functions inside try-clauses isn't allowed in strict
mode and causes a warning at least in Firefox.

Before this fix the debug parameter always prevent the GIF from being
sent even though no actual debug information was returned unless the
allowdebug configuration option was set. Now the GIF is only disabled if
debugging is actually allowed.

FS#2415 add  to mediamanager (refactor pageinfo() and shift MEDIAMANAGER_STARTED after mediainfo() sets up )

Previously the media manager created an empty namespace whenever you
opened a non-existing namespace with upload permissions. Now the current
namespace is only displayed in the tree but not actually created.

this disables the JavaScript compatibility layer which let pre-jQuery
migration plugins run with their old code.

This will break plugins using outdated JavaScript. These plugins have to
be updated according to https://www.dokuwiki.org/devel:jqueryfaq

As a courtesy to users, the compatibility.js is not deleted, yet.
Undoing this single patch can be used as a temporary workaround.

It seems, some servers require a special Status: header for sending the
HTTP status code from PHP (F)CGI to the server. This patch introduces a
new function (adopted from CodeIgniter) for simplifying the status
handling.

Use variable for maximum number of suggestions for quicksearch.
And hide suggestions when search field is emptied, or when no suggestion are found.

When the search input is still only a few characters, the number of matching pages is big.
Browsers have heavy work to progress this whole return, better cut off so only the part that is directly displayed will be sent.

this will be removed soon again. plugins using jQuery should make sure
they are compatible to jQuery 1.9

* jQuery 1.9.0
* jQuery-UI v1.9.2
* jQuery.fn.live > jQuery.fn.on
* jQuery.fn.browser replacement (jquery.mb.browser.js)

Before this change the GIF wasn't sent at all when the PHP settings
indicate that sending of the GIF needs to be deferred and it was sent
when the debug output was on.

the function always returned true, even if no action was taken. This
resulted in no further indexer tasks being run.
