simpletrace: Thread-safe tracing

Trace events outside the global mutex cannot be used with the simple

This patch restructures the simple trace backend with a ring buffer...

New trace-event backend: stderr

This backend sends trace events to standard error output during the emulation.

display the list of available backends.

trace: Format strings must begin/end with double quotes

trace: Use portable format strings

It is not portable to use "%ld" for int64_t because int64_t may have
type long on 64-bit platforms and long long on 32-bit platforms. Use
the standard library PRId64 macros to keep format strings portable.
