Merge Request #29 - 2017-11-17

Fixes

libqi:

• Fixes memory leak in meta-object cache ( #32745, #39208, #39838).

  This memory leak is the biggest mentioned in our tracker and this fix should help in a major way but is not enough to completely close the issue as there are other less important leaks identified.

• Fixes deadlock on some signals disconnection ( #38899);
