perf tools: Persistent events, changes for perf tool integration

This patch set contains userland changes necessary for out-of-the-box support of persistent events. These patches are follow on patches of the kernel patches I sent out today:

[PATCH 00/16] perf, persistent: Kernel updates for perf tool integration

Persistent events are always enabled kernel events. Buffers are mapped readonly and multiple users are allowed. The persistent event flag of the event attribute must be set to specify such an event.

The following changes to perf tools are necessary to support persistent events. A way is needed to specify sysfs entries to set event flags. For this a new syntax 'attr<num>' was added to the event parser, see patch #3. We also need to change perf tools to mmap persistent event buffers readonly.

All patches can be found here:
