trace: Add trace-events file for declaring trace events

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...

trace: Add simple built-in tracing backend

This patch adds a simple tracer which produces binary trace files. To
try out the simple backend:

After running QEMU you can pretty-print the trace:

trace: Support for dynamically enabling/disabling trace events

This patch adds support for dynamically enabling/disabling of trace events.
This is done by internally maintaining each trace event's state, and
permitting logging of data from a trace event only if it is in an...

trace: Support disabled events in trace-events

Sometimes it is useful to disable a trace event. Removing the event

trace_*() function for the event.

This patch makes it easy to build without specific trace events by...
