New trace-event backend: stderr

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

Also add a "--list-backends" option to tracetool, so configure script can
display the list of available backends.

trace: Format strings must begin/end with double quotes

Document the restriction that format strings must begin and end with
double quotes. This is for easy parsing since we don't run cpp over
trace-events.

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.
