Previously, the resource monitor always creates a new Unix

sum of the cpu time measured later is rather reduced than the sum of
the cpu time measured first, and if the cpu usage rate is calculated
using the difference between these two cpu times, a negative result

util: kernel: Fix to return valid result on getting cpu stat

In the case of the target which supports cpu hotplug, the number of
possible online cpus can be changed and thus __get_cpu_stat can be
failed for offline cpus. At worst case if the last __get_cpu_stat is
resulted in negative, kernel_get_per_cpu_stat can return error even
though it is not actual failure. To prevent this situation, this
ignores the case that __get_cpu_stat returns failure.

resource: Add disk and network resource driver

Add disk and network resource driver to provide monitoring data.

1. Add disk resource driver to provide the disk bandwidth
   and usage with following resource attributes:
- DISK_ATTR_NAME indicates the disk device name
- DISK_ATTR_READ_PER_SEC indicates read bandwidth of specific block like zram0
- DISK_ATTR_WRITE_PER_SEC indicates write bandwidth of specific block like mmcblk0
- DISK_ATTR_READ_TOTAL indicates read kB size of specific block
- DISK_ATTR_WRITE_TOTAL indicates write kB size of specific block

The detailed description[1] of data are from /proc/diskstats and
/sys/class/block/[block name]/stats:
[1] https://www.kernel.org/doc/Documentation/ABI/testing/procfs-diskstats

2. Add skeleton of network resource driver with resource name attribute.
- NETWORK_ATTR_NAME indicates the network device name

util: kernel: Check whether adding cpu e/u/stime for TGID taskstat

There are difference with information on TGID taskstat among kernel

commit in mainline linux 8c733420bdd5 ("taskstats: add e/u/stime for TGID command")
is applied.
So, now check TGID taskstat has zero value for e/u/stime at the
initialization, and, if so, those time is calculated by adding values
in PID taskstats.

util: resource: Assign an unique resource id when a new resouce is created

When PASS-daemon restarted unexpectedly, a pass client which is
survived in spite of PASS-daemon's restart can access resources
by using its own resource id (which is valid for previous PASS
daemon).

To prevent this situation, PASS should assign a unique resource
id for each created resource even if PASS daemon is restarted.
To this end, PASS initializes a global resource id (g_resource_id)
by using the value of gettimeofday(). So, each resource will be
assigned time-reflected resource id, and uniqueness is ensured
unless the number of created resources crosses the time consumed
before restarted.
