Bug#876964: ycmd: libclang1-3.9 crashes when ycmd starts after upgrade to version 1:3.9.1-16

[Yllman, Jens]

Yes, the change is probably in libclang1-3.9. But to me it only looks 
like libclang1-3.9 got stricter on reading JSON. In the error message 
you can see the error in the JSON that is sent to libclang1-3.9 from 
ycmd. So, I think it is ycmd that is wrong. But earlier versions of 
libclang1-3.9 was more forgiving. On the other end, libclang1-3.9 should 
not crash on this? But last entry in a list or object of JSON should not 
have a , at the end.
