cfbe9f1201 build: link to glib library
Add the main glib.h to internal.h so that all common code can use it.

Historically glib allowed applications to register an alternative
memory allocator, so mixing g_malloc/g_free with malloc/free was not
safe.

This was feature was dropped in 2.46.0 with:

      commit 3be6ed60aa58095691bd697344765e715a327fc1
      Author: Alexander Larsson <alexl@redhat.com>
      Date:   Sat Jun 27 18:38:42 2015 +0200

        Deprecate and drop support for memory vtables

Applications are still encourged to match g_malloc/g_free, but it is no
longer a mandatory requirement for correctness, just stylistic. This is
explicitly clarified in

    commit 1f24b36607bf708f037396014b2cdbc08d67b275
    Author: Daniel P. Berrangé <berrange@redhat.com>
    Date:   Thu Sep 5 14:37:54 2019 +0100

        gmem: clarify that g_malloc always uses the system allocator

Applications can still use custom allocators in general, but they must
do this by linking to a library that replaces the core malloc/free
implemenentation entirely, instead of via a glib specific call.

This means that libvirt does not need to be concerned about use of
g_malloc/g_free causing an ABI change in the public libary, and can
avoid memory copying when talking to external libraries.

This patch probes for glib, which provides the foundation layer with
a collection of data structures, helper APIs, and platform portability
logic.

Later patches will introduce linkage to gobject which provides the
object type system, built on glib, and gio which providing objects
for various interesting tasks, most notably including DBus client
and server support and portable sockets APIs, but much more too.

4597a23f50 util: change identity class attribute names
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.

8d6eaf5e09 access: fix incorrect addition to virAccessPermNetwork
Commit e69444e17 (first appeared in libvirt-5.5.0) added the new value
"VIR_ACCESS_PERM_NETWORK_SEARCH_PORTS" to the virAccessPerNetwork
enum, and also the string "search_ports" to the VIR_ENUM_IMPL() macro
for that enum. Unfortunately, the enum value was added in the middle
of the list, while the string was added to the end of the
VIR_ENUM_IMPL().

This patch corrects that error by moving the new value to the end of
the enum definition, so that the order matches that of the string
list.

6a4d938dd3 Require a semicolon for VIR_ENUM_IMPL calls
Missing semicolon at the end of macros can confuse some analyzers
(like cppcheck <filename>), and we have a mix of semicolon and
non-semicolon usage through the code. Let's standardize on using
a semicolon for VIR_ENUM_IMPL calls.

Move the verify() statement to the end of the macro and drop
the semicolon, so the compiler will require callers to add a
semicolon.

While we are touching these call sites, standardize on putting
the closing parenth on its own line, as discussed here:

605496be60 access: Modify the VIR_ERR_ACCESS_DENIED to include driverName
https://bugzilla.redhat.com/show_bug.cgi?id=1631606

Changes made to manage and utilize a secondary connection
driver to APIs outside the scope of the primary connection
driver have resulted in some confusion processing polkit rules
since the simple "access denied" error message doesn't provide
enough of a clue when combined with the "authentication failed:
access denied by policy" as to which connection driver refused
or failed the ACL check.

In order to provide some context, let's modify the existing
"access denied" error returned from the various vir*EnsureACL
API's to provide the connection driver name that is causing
the failure. This should provide the context for writing the
polkit rules that would allow access via the driver, but yet
still adhere to the virAccessManagerSanitizeError commentary
regarding not telling the user why access was denied.

6ef65e3c96 access: Fix nwfilter-binding ACL access API name generation
https://bugzilla.redhat.com/show_bug.cgi?id=1611320

Generation of the ACL API policy is a "automated process"
based on this perl script which "worked" with the changes to
add nwfilter binding API's because they had the "nwfilter"
prefix; however, the generated output name was incorrect
based on the remote protocol algorithm which expected to
generate names such as 'nwfilter-binding.action' instead
of 'nwfilter.binding-action'.

This effectively changes src/access/org.libvirt.api.policy entries:

  org.libvirt.api.nwfilter.binding-create ==>
      org.libvirt.api.nwfilter-binding.create

  org.libvirt.api.nwfilter.binding-delete ==>
      org.libvirt.api.nwfilter-binding.delete

  org.libvirt.api.nwfilter.binding-getattr ==>
      org.libvirt.api.nwfilter-binding.getattr

  org.libvirt.api.nwfilter.binding-read ==>

10f94828ea virobject: Introduce VIR_CLASS_NEW() macro
So far we are repeating the following lines over and over:

  if (!(virSomeObjectClass = virClassNew(virClassForObject(),

      return -1;

While this works, it is impossible to do some checking. Firstly,
the class name (the 2nd argument) doesn't match the name in the
code in all cases (the 3rd argument). Secondly, the current style
is needlessly verbose. This commit turns example into following:

  if (!(VIR_CLASS_NEW(virSomeObject,
                      virClassForObject)))
      return -1;
