uid_cputime: fix cputime overflow
Converting cputime_t to usec caused overflow when the value is greater
than 1 hour. Use msec and convert to unsigned long long to support bigger
range.

uid_cputime: Avoids double accounting of process stime, utime and cpu_power in
task exit.
This avoids the race where a particular process is terminating and we
read the show_uid_stats. At this time since the task_struct still exists
and we will account for the terminating process as one of the active
task, where as the stats would have been added in the task exit
callback.

uid_cputime: Extends the cputime functionality to report power per uid
/proc/uid_cputime/show_uid_stats shows a third field power for each of
the uids. It represents the power in the units (uAusec)

proc: uid: Adds accounting for the cputimes per uid.
Adds proc files /proc/uid_cputime/show_uid_stat and
/proc/uid_cputime/remove_uid_range.
show_uid_stat lists the total utime and stime for the active as well as
terminated processes for each of the uids.
Writing a range of uids to remove_uid_range will delete the accounting
for all the uids within that range.
