trace: Provide a per-event status define for conditional compilation

Adds a 'TRACE_${NAME}_ENABLED' preprocessor define for each tracing event in
"trace.h".

This lets the user conditionally compile code with a relatively high execution
cost that is only necessary when producing the tracing information for an event...

tracetool: Omit useless QEMU_*_ENABLED() check

SystemTap provides a "semaphore" that can optionally be tested before
executing a trace event. The purpose of this mechanism is to skip
expensive tracing code when the trace event is disabled.

For example, some applications may have trace events that format or...

qerror: add check-qerror.sh to verify alphabetical order

We're supposed to keep qerror definitions and table entries in
alphabetical order. In practice this is not checked.

I haven't found a nice way to integrate this into the makefile yet but

Fix qapi code generation fix

The fixes to qapi code generation had multiple bugs:
- the Null class used to drop output was missing some methods

- the --source and --header options were swapped...

Fix qapi code generation wrt parallel build

Make's multiple output syntax

x.c x.h: x.template
gen < x.template

actually invokes the command once for x.c and once for x.h (with differing $@
in each invocation). During a parallel build, the two commands may be invoked...

scripts/analyse-9p-simpletrace.py: Add symbolic names for 9p operations.

Currently, we just print the numerical value of 9p operation identifier in
case of RERROR which is less meaningful for readability. Mapping 9p
operation ids to symbolic names provides a better tracelog:...

vl.c: In qemu -h output, only print options for the arch we are running as

Only print options in the help output that are accepted by our arch.
This is less confusing for users and also for other programs that
consume the help output.

The options affected are:...
