Stanislav Fomichev 1e28fe0a4f perf trace: Add pagefaults record and replay support
Previous commit added live pagefault trace support, this one adds record
and replay support.

Example:

  [root@zoo /]# echo 1 > /proc/sys/vm/drop_caches ; trace -F all record -a sleep 10
  [ perf record: Woken up 0 times to write data ]
  [ perf record: Captured and wrote 1029.722 MB perf.data (~44989242 samples) ]

  [root@zoo /]# ls -la perf.data
  -rw-------. 1 root root 1083921722 Jun 26 17:44 perf.data

  [root@zoo /]# perf evlist
  raw_syscalls:sys_enter
  raw_syscalls:sys_exit
  major-faults
  minor-faults

  [root@zoo /]# trace -i perf.data | grep -v trace\/ | tail -15
