Support QNX (unoffically)

Allow to build for QNX and run in single-process mode. There are a
few limitations, e.g. filesystem mount monitoring and startup timer
are not supported and there's only a rudimentary stack trace in case
of a crash, etc.

Since Qt Network doesn't provide a HW address it has to be passed
to qmake with, e.g.: -config hardware-id=dummyHwId

(this is a manual reimplementation of
Ia58d09d15a781666fe788f21dfe9c7af7a2a74ef and part of
I8057bc23fd0072c997c8a42539ef23a6c7a9e28a from the dev branch)
