[Tizen]Remove the openssl BuildRequires

Chromium has its openssl in thirdparty, so there should be no dependency on
Tizen's openssl
[Application][Linux] xwalkctl should fail if can't activate service

When listing the applications, we were missing a case in which the
service wasn't activated but listing continued without errors. We prefer
to fail as soon as possible in the tool.
[Application][Tizen] Specify session bus address in Tizen

In Tizen the session bus is not available for us by peeking at the
DBUS_SESSION_BUS_ADDRESS, it will be created in a well-known place
instead.

The code change so instead of using the '_for_bus' variants of the
functions, we explicit create the GDBusConnection and use it.

This patch also improves the error message for the case where we fail to
create the object manager client and fix the include rules to follow our
standards.

Fix compilation error with -Werror=delete-non-virtual-dtor flag set

Added a virtual destructor to the local RunAsBrowser() 'Observer' class (even though it is not needed there) so that compiler does not complain.

[Runtime] Move "is_running_as_service" flag to XWalkRunner

This distinction will be used later in xwalk_paths, to setup different
data paths for Crosswalk in Tizen.
[Runtime] Small refactor to our PathProvider

Move the logic for xwalk::DIR_DATA_PATH to a separate function, and
create a helper function for Linux for getting the config path from
XDG. These will be useful when we transition Tizen to use home directory
for service mode instead of the "/opt/usr/apps".

Revert "[Tizen]Remove the openssl BuildRequires"

The code in crypto/crypto.gyp only pulls in the dependency on
third_party/openssl when building for Android.

For now, revert the commit as it was not essential while we can fix this
upstream.

This reverts commit f8d9749eb4320d49527184214df1d028e242d7b7.

[Application][D-Bus] Add the concept of an Running Application Object

This object will be used to keep track of running application lifetimes
and on later commits to follow the launcher bus name, so when it exits
the bus the applications is automatically killed.
[Applications][D-Bus] Follow the xwalk-launcher D-Bus name

When the process that called Launch() on 'org.crosswalkproject.Running.Manager'
(typically xwalk-launcher) exits the bus (usually meaning that it was killed by
some kind of task manager) we need that the launched application also to exit.

We keep listening for the 'NameOwnerChanged' signal for the sender of the 'Launch()'
and when we receive a signal for that sender, with an empty new value (signifying
that there's no one with that name) we kill the application.
[Applications][D-Bus] Only allow the launcher of the application to call Terminate()

We don't want other processes to kill others' applications, so we restrict the
calling of Terminate() to the process that caused the application creation.
