[Releasing] Branching from '5.10' to '5.10.1' started

[Jani Heikkinen]

Hi all,

We have soft branched '5.10.1' from '5.10' on Friday. Target is to do final downmerge from '5.10' -> '5.10.1' Friday 2.2.2018. Please finalize ongoing changes in '5.10' and start using '5.10.1' for new changes. 
First Qt 5.10.1 snapshot is already under testing and we are targeting to get Qt 5.10.1 out as soon as possible after final downmerge. So please minimize changes for Qt 5.10.1 from now on to get it out quickly!

br,
Jani
