monitor: lib: Support Unix domain socket (UDS) and TCP/IP socket concurrently

Previous TCP/IP socket-based IPC has a security issue that
anyone can access the opened port without credential. Since
UDS is exported as a file, we can apply file-based access
control to it. So, we use UDS instead of TCP/IP socket by
default.

At the same time, we also support TCP/IP socket for
resource-monitor-tool which is a web-based monitoring tool
in user space. In the future, we will support TCP/IP socket
only in debugging mode which is turned on/off by root-
privileged command line tool.

resource: display: Add a display monitor thread to deal with multiple clients

When multiple clients request to get fps concurrently,
unacceptable delays (upto tens of seconds for hundred
clients) are incurred. I guess that the dbus function
g_dbus_connection_send_message_with_reply_sync() cannot
deal with multiple concurrent calls.

This patch added a monitor thread to read current fps

clients. By doing so, multiple clients can get the fps

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.

Actually, it is difficult and complicated to specify
whether some property is mandatory or optional even if
it is requied.

Specify either mandatory or optional status of each property
with get_property() function. If some property is mandatory,
just pass the true into 3rd argument of get_property.

In case of mandatory property, get_property returns error
if property is absent. On the other hand, get_property
returns non-zero with debug level log about absent property.

And also, should print the error for non-existent mandatory properteis
in same section at the same time. It helps user to fix
the configuration.

For example,
- 'device_type' and 'device_name' properties are mandatory
   and 'thermal_device_name' property is optional property.

ret += get_property(obj, "device_type", DATA_TYPE_STRING,

ret += get_property(obj, "device_name", DATA_TYPE_STRING,
true, (void *)device_name);
ret += get_property(obj, "thermal_device_name", DATA_TYPE_STRING,
false, (void *)thermal_device_name);

if (ret < 0) {

    return ret;
}

- result of error log
