perf tools: Allow multiple threads or processes in record, stat, top
...
Allow a user to collect events for multiple threads or processes
using a comma separated list.
e.g., collect data on a VM and its vhost thread:
perf top -p 21483,21485
perf stat -p 21483,21485 -ddd
perf record -p 21483,21485
or monitoring vcpu threads
perf top -t 21488,21489
perf stat -t 21488,21489 -ddd
perf record -t 21488,21489

perf tools: Introduce per user view
...
The new --uid command line option will show only the tasks for a given
user, using the proc interface to figure out the existing tasks.
Kernel work is needed to close races at startup, but this should already
be useful in many use cases.

perf threads: Move thread_map to separate file
...
To untangle it from struct thread handling, that is tied to symbols, etc.
Right now in the python bindings I'm working on I need just a subset of
the util/ files, untangling it allows me to do that.
