perf tools: Add support to parse event group syntax
Adding scanner/parser bits to parse event groups.
The grammar for group is:
groups: groups ',' group | group
group: group_name '{' events '}' group_mod
group_name: name | empty
group_mod: ':' group_mods | empty
group_mods: event_mod
It's possible to use standard event modifier as a modifier
for group. It'll be used as an update to existing event
modifiers.
It's necessary to use quoting ("'\) when specifying group on
command line, since {} characters are interpreted by most of
the shells.
It is now possible to specify groups in event syntax like:
'{cycles,faults}'
- anonymous group
'group1{cycles,faults}
- group with name 'group1'
'{cycles,faults}:k
- anonymous group with event modifier 'k'
'{cpu-clock,task-clock},{minor-faults,major-faults}'
- two anonymous groups
The grouping functionality itself is coming shortly.
