If giving QEMU a log arg which asks to enable multiple
different trace event patterns such as
$QEMU -d trace:qio*,trace:qcrypto*
the parser will then invoke
trace_enable_events("qio*,trace:qcrypto*")
trace_enable_events("qcrypto*")
as when finding a 'trace:' prefix, it is not clever
enough to strip anything after the next comma. As
a result only the last 'trace:' match ever works.
Rather than trying to be more clever with parsing the
command line arg in place, simplify the code by
using g_strsplit to break it into individual strings
on ','. These resulting pieces can be directly used
without worrying about trailing data from the next
option.
