core: Replace functionalities based on Ecore with ones based on GLib

Since Ecore library is tightly coupled with EFL which is a set of
graphics libraries, for the devices without GUI, so called 'headless
devices', even if the system only requires the functionalities provided
by Ecore, many unnecessary packages should be included in it. This could
make the size of the platform image bigger. For this reason, we decided
to reimplement all the functionalites based on Ecore of PASS using GLib.

This patch replaces the functionalites based on Ecore with ones based on
GLib. In detail, the ecore main loop is changed to the glib main loop
and the ecore timer-based task handling is now changed to the glib
timeout-based task handling mechanism. In addition, in order to support
DBus IPC, PASS uses gdbus now instead of edbus. The code based on gdbus
which was implemented the old-fashioned way is also refactored by this
patch.

pass: Skip exit process for uninitialized resources

Even in the case that the resource is not initialized due to any
reason, pass tries to exit that resource during service stop, and
thus it causes failure on exit process. To resolve it, this patch
adds the state of resource and set UNUSED state to resource on error
case. After that, exit process for the resource in UNUSED state will
be skipped.

core: Refactor macros which wrap the g_list functions in list.h

In list.h, there are a group of macro definitions started with the prefix
'DD_LIST'. Most of these macros are neither meaningful nor necessary
since they just wrap the corresponding g_list functions. For this
reason, this patch removes those wrapping macros. In addition, the
prefix 'DD_LIST' is ambiguous. This patch also changes the prefix

pass: hal: Fix build warning caused by a wrong scanf format specifier

The original type of int64_t depends on whether 32-bit or 64-bit
environment. In detail, on the 32-bit environment, int64_t is long long
int while, on the 64-bit environment, it is long int. Therefore, using
%lld for the scanf format specifier of int64_t on the 64-bit environment
causes a build warning. This patch fixes the following build warning [1]
using the special purpose format specifier, SCNd64, for int64_t.

[1] "warning: format '%lld' expects
argument of type 'long long int *', but argument 3 has type 'int64_t *

pmqos: Fix build warning caused by mis-type casting

This patch fixes a build warning caused by mis-type casting from a
pointer to a int type while building the package for aarch64. On the
32-bit environment, the size of a pointer is 4 bytes which is the same
size of a int type. However, on the other hand, on the 64-bit
environment, the size of a pointer is 8 bytes while the size of a int
type is still 4 bytes. This is the main reason of the build warning.

According to the booting_done_received function in sre/core/boot.c, a
pointer of the int variable, done, is passed as the first argument, a
void pointer, of the notifier call back functions. Therefore, such type
casting from a void pointer to int is unnecssary and seems to be buggy.
This patch modifies it to cast the type from void pointer to int
pointer.

scripts: Apply dbus security policy using xml-based conf file

Until now, there is no specific dbus security policy in PASS. Therefore,
any processes which do not have the root or special privileges can send
dbus messages to the pass daemon. This could be a serious security hole.
In order to solve such problem, this patch applies a dbus security
policy by using the pass.conf file, which is formed in XML format.

From now, without the root privileges, it is not allowed to send dbus
messages to the pass daemon. Only dbus messages sent from the processes
whose user ids are *app_fw* to the pmqos interface can be received by
the pass daemon.

pmqos: Fix bug of 'support' property of pass-pmqos.conf

This patch fixes the bug related to 'support' property of pass-pmqos.conf.

PASS PMQoS has the pass-pmqos.conf which contains the supported scenario
name and the number of supported scenarios. Each scenario has the 'support'
property indicating whether scenario is supported or not on platform.

If the 'support' property value is changed from 'yes' to 'no',
PASS shows the following error log during the init step.
