qom: Upgrade to 2.0.0 version

This also makes android-configure.h generate a new header,
trace/generated-tracers.h that contains definitions for static
inline and empty tracing functions. The header is generated from
the file 'trace-events', processed by scripts/tracetool.py which
both come from upstream.

Note that a few calls to obsolete trace_xxx() functions are still
commented out in the code though.
