The git master of horde_dav already has a bundled sabredav 2.1.10 while
the latest proper release has 1.8.12.
For my upgrade project, I will unbundle sabredav and use composer.

As FRAMEWORK_5_2 has a bc requirement to run on PEAR and on PHP 5.3, it
would be incompatible anyway. Modern sabredav requires PHP 7
