46ec5f85c8 Convert public datatypes to inherit from virObject
This converts the following public API datatypes to use the
virObject infrastructure:

  virConnectPtr
  virDomainPtr
  virDomainSnapshotPtr
  virInterfacePtr
  virNetworkPtr
  virNodeDevicePtr
  virNWFilterPtr
  virSecretPtr
  virStreamPtr
  virStorageVolPtr
  virStoragePoolPtr

The code is significantly simplified, since the mutex in the
virConnectPtr object now only needs to be held when accessing
the per-connection virError object instance. All other operations
are completely lock free.

* src/datatypes.c, src/datatypes.h, src/libvirt.c: Convert
  public datatypes to use virObject
* src/conf/domain_event.c, src/phyp/phyp_driver.c,
  src/qemu/qemu_command.c, src/qemu/qemu_migration.c,

  tests/qemuxml2argvtest.c, tests/qemuxmlnstest.c,

  to use virObjectUnref/virObjectRef

6ed5a1b9bd Add public API to register a callback to be invoked on connection close
Define new virConnect{Register,Unregister}CloseCallback() public APIs
which allows registering/unregistering a callback to be invoked when
the connection to a hypervisor is closed. The callback is provided
with the reason for the close, which may be 'error', 'eof', 'client'
or 'keepalive'.

f9ce7dad60 Desert the FSF address in copyright
Per the FSF address could be changed from time to time, and GNU
recommends the following now: (http://www.gnu.org/licenses/gpl-howto.html)

  You should have received a copy of the GNU General Public License
  along with Foobar.  If not, see <http://www.gnu.org/licenses/>.

This patch removes the explicit FSF address, and uses above instead
(of course, with inserting 'Lesser' before 'General').

Except a bunch of files for security driver, all others are changed
automatically, the copyright for securify files are not complete,
that's why to do it manually:

  src/security/security_selinux.h
  src/security/security_driver.h

  src/security/security_apparmor.h

9f748277bb Fixed URI parsing
Function xmlParseURI does not remove square brackets around IPv6
address when parsing. One of the solutions is making wrappers around
functions working with xmlURI*. This assures that uri->server will be
always properly assigned and it doesn't have to be changed when used
on some new place in the code.
For this purpose, functions virParseURI and virSaveURI were
added. These function are wrappers around xmlParseURI and xmlSaveUri
respectively.
Also there is one new syntax check function to prohibit these functions
anywhere else.

File changes:
 - src/util/viruri.h        -- declaration
 - src/util/viruri.c        -- definition
 - src/libvirt_private.syms -- symbol export
 - src/Makefile.am          -- added source and header files
 - cfg.mk                   -- added sc_prohibit_xmlURI
 - all others               -- ID name and include fixes

aa286e537d virStorageVol: avoid PATH_MAX-sized array
POSIX allows implementations where PATH_MAX is undefined, leading
to compilation error.  Not to mention that even if it is defined,
it is often wasteful in relation to the amount of data being stored.

All clients of vol->key were audited, and found not to care about
whether key is static or dynamic, except for these offenders:

* src/datatypes.h (struct _virStorageVol): Manage key dynamically.
* src/datatypes.c (virReleaseStorageVol): Free key.
(virGetStorageVol): Copy key.

2ff4c13754 Remove all object hashtable caches from virConnectPtr
The virConnectPtr struct will cache instances of all other
objects. APIs like virDomainLookupByUUID will return a
cached object, so if you do virDomainLookupByUUID twice in
a row, you'll get the same exact virDomainPtr instance.

This does not have any performance benefit, since the actual
logic in virDomainLookupByUUID (and other APIs returning
virDomainPtr, etc instances) is not short-circuited. All
it does is to ensure there is only one single virDomainPtr
in existance for any given UUID.

The caching has a number of downsides though, all relating
to stale data. If APIs aren't careful to always overwrite
the 'id' field in virDomainPtr it may become out of data.
Likewise for the name field, if a guest is renamed, or if
a guest is deleted, and then a new one created with the
same UUID but different name.

This has been an ongoing, endless source of bugs for all
applications using libvirt from languages with garbage
collection, causing them to get virDomainPtr instances
from long ago with stale data.

The caching is also a waste of memory resources, since
both applications, and language bindings often maintain
their own hashtable caches of object instances.

This patch removes all the hash table caching, so all
APIs return brand new virDomainPtr (etc) object instances.

* src/datatypes.h: Delete all hash tables.
* src/datatypes.c: Remove all object caching code

2c0db5b5dc Simplify "NWFilterPool" to "NWFilter"
The public object is called NWFilter but the corresponding private
object is called NWFilterPool. I don't see compelling reasons for this
Pool suffix. One might argue that an NWFilter is a "pool" of rules, etc.

Remove the Pool suffix from NWFilterPool. No functional change included.
