trace: Update docs to use example events that exist

The events 'qemu_malloc' and 'qemu_free' used in the examples no longer exist,
so use 'qemu_vmalloc' and 'qemu_vfree' instead.

trace: allow trace events with string arguments

String arguments are useful for producing human-readable traces without
post-processing (e.g. stderr backend). Although the simple backend
cannot handles strings all others can. Strings should be allowed and...

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:...

trace: always compile support for controlling and querying trace event states

The current interface is generic for this small set of operations, and thus
other backends can easily modify the "trace/control.c" file to add their own
implementation.

trace: add "-trace events" argument to control initial state

The "-trace events" argument can be used to provide a file with a list of trace
event names that will be enabled prior to starting execution, thus providing
early tracing.

This saves the user from manually toggling event states through the monitor...

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).

trace: [stderr] add support for dynamically enabling/disabling events

Uses the generic interface provided in "trace/control.h" in order to provide
a programmatic interface as well as command line and monitor controls.
