trace: allow PRI*64 at beginning and ending of format string

The tracetool parser only picks up PRI*64 and other format string macros
when enclosed between double quoted strings. Lift this restriction by
extracting everything after the closing ')' as the format string:...

    name)

trace: always use the "nop" backend on events with the "disable" keyword

Any event with the keyword/property "disable" generates an empty trace event
using the "nop" backend, regardless of the current backend.

trace: [simple] disable all trace points by default

Note that this refers to the backend-specific state (whether the output must be
generated), not the event "disabled" property (which always uses the "nop"
backend).

tracetool: allow ) in trace output string

Be greedy in matching the trailing "\)*" pattern. Otherwise, all the
text in the trace string up to the last closed parenthesis is taken as
part of the prototype.

tracetool: Add optional argument to specify dtrace probe names

Optional feature allowing a user to generate the probe list to match
the name of the binary, in case they wish to install qemu under a
different name than qemu-{system,user},<arch>

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.
