Remove the "UNIX" tag from the names for user name, group name,
process ID and process time, since these attributes are all usable
for non-UNIX platforms like Windows.
User ID and group ID are left with a "UNIX" tag, since there's no
equivalent on Windows. The closest equivalent concept on Windows,
SID, is a struct containing a number of integer fields, which is
commonly represented in string format instead. This would require
a separate attribute, and is left for a future exercise, since
the daemons are not currently built on Windows anyway.

When using the fine grained access control mechanism for APIs, when a
client connects to libvirtd, the latter will fetch the uid, gid, selinux
info of the remote client on the UNIX domain socket. This is then used
as the identity when checking ACLs.
With the new split daemons things are a bit more complicated. The user
can connect to virtproxyd, which in turn connects to virtqemud. When
virtqemud requests the identity over the UNIX domain socket, it will
get the identity that virtproxyd is running as, not the identity of
the real end user/application.
virproxyd knows what the real identity is, and needs to be able to
forward this information to virtqemud. The virConnectSetIdentity API
provides a mechanism for doing this. Obviously virtqemud should not
accept such identity overrides from any client, it must only honour it
from a trusted client, aka one running as the same uid/gid as itself.
The typed parameters exposed in the API are the same as those currently
supported by the internal virIdentity class, with a few small name
changes.

Since the introduction of the virNetworkPort object, the network driver
has a persistent record of ports that have been created against the
networks. Thus the hypervisor drivers no longer communicate to the
network driver during libvirtd restart.
This change, however, meant that the connection usage counts were
no longer re-initialized during a libvirtd restart. To deal with this we
must iterate over all virNetworkPortDefPtr objects we have and invoke
the notify callback to record the connection usage count.

The LIBVIRT_RESULT function takes two or three arguments. The
first one is the name of the result (aka CHECK_NAME). It is
printed before the colon character. The rest of the arguments is
printed after the character. To produce colourized output a
couple of changes needs to be made.
Firstly, we need to print the CHECK_NAME using "echo -n" so that
the new line is not appended at the end of the message. To
achieve this, AS_MESSAGE_N function is introduced. It's a
verbatim copy of AS_MESSAGE (which is just another alias to
AC_MSG_NOTICE) except it doesn't put '\n' at the EOL.
The alias is defined at /usr/share/autoconf-*/autoconf/general.m4
and the AS_MESSAGE is then defined at
/usr/share/autoconf-2.69/m4sugar/m4sh.m4.
Secondly, the rest of the arguments are printed colourized and to
achieve that and also keep printing them into the log file the
_AS_ECHO and COLORIZE_RESULT functions need to be called.
