trace_idx is always in the range [0, TRACE_BUF_LEN). There is no need
to perform this test.

Whitespace "i=0; i<max_idx ;i++". "i = 0; i < max_idx; i++" is pretty
common across QEMU.

Getting only numeric output is the limitation of a binary trace. It
would probably be possible to pretty-print without much additional code
by using the format strings from the trace-events file.
I think the numeric dump is good for now though. Hex is more compact
than decimal and would make pointers easier to spot. Want to change
this?

qemu-common.h forward-declares Monitor, I don't think you need
monitor.h.
