Re-think Linux vs mobile ifdefs a bit. Use #ifdef __linux only to
surround code that actually is Linux-specific. Use #ifdef MOBILEAPP
for code that is for a mobile version (with no separste wsd, forkit,
and kit processes, and with no WebSocket protocol used).
Bypass UnitFoo for mobile. Possibly we do want the UnitFoo stuff after
all on mobile, to run in some special testing mode? Hard to say, let's
skipt it for now.
Two problem types:
- non-final class has virtual functions but no virtual dtor -> mark the
class final
- abstract class has no virtual dtor -> add a virtual dtor
