This series add support for trace events grouping. The state of a given group
of trace events can be queried or changed in bulk by the following monitor
commands:
* info trace-groups
View available trace event groups and their state. State 1 means enabled,
state 0 means disabled.
* trace-group NAME on|off
Enable/disable a given trace event group.
A group of trace events can also be enabled in early running stage through
adding its group name prefixed with "group:" to trace events list file
which is passed to "-trace events".
Change from V1:
* fix coding style problems
* rebase against latest master
