Alex Bennée 78f314cf83 trace-events: remove the remaining vcpu trace events
While these are all in helper functions being designated vcpu events
complicates the removal of the dynamic vcpu state code. TCG plugins
allow you to instrument vcpu_[init|exit|idle].

We rename cpu_reset and make it a normal trace point.

# See docs/devel/tracing.rst for syntax documentation.

# This file is processed by the tracetool script during the build.
#
# To add a new trace event:
#
# 1. Choose a name for the trace event. Declare its arguments and format
# string.
#
# 2. Call the trace event from code using trace_##name, e.g. multiwrite_cb() ->
# trace_multiwrite_cb(). The source file must #include "trace.h".
#
# Format of a trace event:
#
# [disable] <name>(<type1> <arg1>[, <type2> <arg2>] ...) "<format-string>"
#
# Example: g_malloc(size_t size) "size %zu"
#
# The "disable" keyword will build without the trace event.
#
# The <name> must be a valid as a C function name.
#
# Types should be standard C types. Use void * for pointers because the trace
# system may not have the necessary headers included.
#
# The <format-string> should be a sprintf()-compatible format string.
