Mount namespace enhancements & fixes

With this release, versioning differs from branch tizen_5.5.

With this release, Tizen has 3 mechanisms for controlling internet access:

* nether
  - supports mutltiuser
  - allows dynamic policy change for app, during application runtime
  - complicated support for many protocols, many dependencies (mostly in kernel)
* iptables + privilege-to-GID mapping
  - supports multiuser
  - dissallows dynamic policy change
  - requires patches from upstream kernel & iptables
* privilege-to-Smack mapping
  - allows dynamic policy change
  - doesn't require any custom kernel changes
  - doesn't support simultaneous multiuser

Reintroduce checks for directory existance in sharedRO setup

While directories connected with per-app sharedRO should exist

previous behaviour of security-manager allowed these dirs

(pre-1.5.18 versions).

On already released product images, some apps, improperly installed

could be already running in the wilderness. Update to new
security-manager, while true to original sharedRO-bind-mount design
(dirs SHOULD exist as designed), may introduce runtime errors.

This patch reintroduces existance checks for directories which are
arguments to bind mounts.

Alternative to this patch would be a migration script that would be much more
complicated and should be accompanied with security-manager commandline tool
used to update DB contents OR appfw script that would re-do the directory

Remove nss plugin IPC with security-manager daemon

Communication was needed to ensure the GID list is calculated based on
Cynara's privilege DB, which contains also per-user information of allowed
privileges.

It was agreed among security and platform teams that system daemons
have statically defined list of GIDs/privileges that doesn't change
over time and also, that this list is the same regardless of the user type
(gumd defines various user types).

This patch changes meaning of per-user-type policy files and Cynara's
per-user-type policy buckets. From now on, the Cynara policy for given user
is applicable as-is only for that user's applications. The user-level
& system-level daemons that may run with "User", "System" or "System::Privileged"
Smack labels have no longer their policy consulted with Cynara.
Instead, they are being given all the privilege-mapped GIDs, with exception
of GIDs that can be mapped to:

http://tizen.org/privilege/internal/livecoredump (priv_livecoredump)
http://tizen.org/privilege/internal/sysadmin (currently no GID associated)

These privileges are used by system team to control inter-service
access to certain DBus interfaces and if any GID is associated with them,
that GID should not be granted by nss plugin. Instead, that GID should
be added as supplementary group of particular service that should be granted
corresponding privilege (ie. using systemd service file or by assigning GID
as supplementary to UID under which the service is running).

When systemd SupplementaryGroup option in service files will be used

Disable tizen.org/privilege/internal/sysadmin for non-applications

By default, system (&user-session) services were granted access to all privileges.
As we work towards fine-grained access control for system services, we need
to disable granting all privileges for services.

This 1st experimental step disables the sysadmin privilege, to be used
to control access to activationd daemon.

For internal applications, sysadmin privilege will be used in manifests, so
Cynara will be able to find exact match for applications' Smack label
in its manifest bucket; for policy evaluation to return success in such case,
all is needed is addition of this new privilege to user-types whitelists
(*.profile files).

For system services, access control to activationd will be limited
to list of user-IDs listed in DBus policy, hence the privilege can't
be automatically enabled for processes with labels User, System & System::Privileged.

For user-session services, this privilege will not be used at the moment.

The (possible) target solution for providing per-service access control
can be based on supplementary groups defined in systemd service files
(or applied as a conequence of cynara policy by security-manager nss plugin).

However, using supplementary groups with DBus policy is not possible at the moment
as both: kernel and DBus will have to be patched to use SO_PEERGROUPS (1)

Fix for synchronization of per-thread mount namespace setup

According to manual (1):

A process may not be reassociated with a new mount namespace
if it is multithreaded.

Also, unshare system call (2) is only creating new namespace
for the caller thread. This means that application candidate
processes that have more than 1 thread are doomed to always have
some threads still in the main mount namespace, without
enforcement of privilege policy connected to mount namespaces.
This renders the mount-namespace-based access control a bad solution.

This patch introduces a special API call to be used by app launchers
just to prepare app candidate processes. This API call doesn't take
any arguments - it just checks if mount-namespaces are enabled
and if yes, just calls unshare(), checking beforehand if the process
has only one thread.
