contrib/plugins/uftrace: implement tracing
We implement tracing, following uftrace format.
Trace is flushed every 32 MB, so file operations don't impact
performance at runtime.
A different trace is generated per cpu, and we ensure they have a unique
name, based on vcpu_index, while keeping room for privilege level coming
in next commit.
Uftrace format is not officially documented, but it can be found here:
