Add a SECURITY LABEL command.

Browse Source 
This is intended as infrastructure to support integration with label-based
mandatory access control systems such as SE-Linux. Further changes (mostly
hooks) will be needed, but this is a big chunk of it.

<title>Description</title>
<para>
<command>SECURITY LABEL</command> applies a security label to a database
object. An arbitrary number of security labels, one per label provider, can
be associated with a given database object. Label providers are loadable
modules which register themselves by using the function
<function>register_label_provider</>.
</para>
<note>
<para>
<function>register_label_provider</> is not an SQL function; it can
only be called from C code loaded into the backend.
</para>
</note>
<para>
The label provider determines whether a given a label is valid and whether
it is permissible to assign that label to a given object. The meaning of a
given label is likewise at the discretion of the label provider.
<productname>PostgreSQL</> places no restrictions on whether or how a
label provider must interpret security labels; it merely provides a
mechanism for storing them. In practice, this facility is intended to allow
integration with label-based mandatory access control (MAC) systems such as
<productname>SE-Linux</>. Such systems make all access control decisions
based on object labels, rather than traditional discretionary access control
(DAC) concepts such as users and groups.
