Enhanced setup check for libxml 2.7.0

Nextcloud version: 9.0.50 (stable)

the loaded libxml is version 2.9.2 but nextcloud can not start.

example:

[~] # /mnt/ext/opt/apache/bin/php -i|grep libXML
libXML support => active
libXML Compiled Version => 2.6.30
libXML Loaded Version => 20902
libXML streams => enabled

https://github.com/nextcloud/server/blob/stable9/lib/private/util.php

if(function_exists('xml_parser_create') &&
    version_compare('2.7.0', LIBXML_DOTTED_VERSION) === 1) {
    $errors[] = array(
        'error' => $l->t('libxml2 2.7.0 is at least required. Currently %s is installed.', [LIBXML_DOTTED_VERSION]),
        'hint' => $l->t('To fix this issue update your libxml2 version and restart your web server.')
    );
}

There is no check which version is loaded!
"LIBXML_DOTTED_VERSION" is not equal "LIBXML_LOADED_VERSION"

if i edit "/lib/private/util.php"
and change "LIBXML_DOTTED_VERSION" to "LIBXML_LOADED_VERSION" nextcloud started.

I have a Qnap NAS. There is only limited possible to install other software.
so it will be also on devices from other manufacturers.

sorry, my english is to bad. i hope you understand me

I just checked this. I can't find any documentation for this constant in http://php.net/manual/en/libxml.constants.php

But a local test showed, that it is available:

    [LIBXML_DOTTED_VERSION] => 2.9.4
    [LIBXML_LOADED_VERSION] => 20904

It looks like the compiled version is older and a newer one is loaded. We also then need to adjust the if statement to something like:

if(LIBXML_LOADED_VERSION >= 20700) {

@LukasReschke Does this makes sense? Should there be an additional check?

"LIBXML_LOADED_VERSION" is a new global constant since PHP 5.3
http://php.net/manual/en/migration53.global-constants.php

Thanks :) I will then try to fix this :)
