85c66be101 perf tools: Introduce tools/lib/lk library
This introduces the tools/lib/lk library, that will gradually have the
routines that now are used in tools/perf/ and other tools and that can
be shared.

Start by carving out debugfs routines for general use.

3ab484b862 perf tools: Add missing files to build the python binding
Changeset 0f6a3015:
"perf tools: Support user regs and stack in sample parsing"

uses hweight_long in evsel.c, so we need to drag util/hweight.c
to the python binding.

Ditto for ee8dd3c:
"perf tools: Change strlist to use the new rblist"

where we need to add util/rblist.c.

Now twatch.py works again:

b52956c961 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

6a5c13aff4 perf tools: Fix build dependency of perf python extension
The perf python extention (perf.so) file lacks its dependencies in the
Makefile so that it cannot be refreshed if one of source files it depends
is changed. Fix it by putting them in a separate file and processing it in
both of Makefile and setup.py.
