[PATCH 3/7] trace: Add simple built-in tracing backend

This patch adds a simple tracer which produces binary trace files and is built into QEMU. The main purpose of this patch is to show how new tracing backends can be added to tracetool. To try out the simple backend: ./configure --trace-backend=simple make After running QEMU you can pretty-print

This patch introduces the trace-events file where trace events can be declared like so: qemu_malloc(size_t size) "size %zu" qemu_free(void *ptr) "ptr %p" These trace event declarations are processed by a new tool called tracetool to generate code for the trace events. Trace event declarations ar
