build: probe for glib-2 library in configure Prepare for linking with glib by probing for it at configure time. Per supported platforms target, the min glib versions on relevant distros are: RHEL-8: 2.56.1 RHEL-7: 2.50.3 Debian (Buster): 2.58.3 Debian (Stretch): 2.50.3 OpenBSD (Ports): 2.58.3 FreeBSD (Ports): 2.56.3 OpenSUSE Leap 15: 2.54.3 SLE12-SP2: 2.48.2 Ubuntu (Xenial): 2.48.0 macOS (Homebrew): 2.56.0 This suggests that a minimum glib of 2.48 is a reasonable target. This aligns with the minimum version required by qemu too. We must disable the bad-function-cast warning as various GLib APIs and macros will trigger this.

util: convert virIdentity class to use GObject Converting from virObject to GObject is reasonably straightforward, as illustrated by this patch for virIdentity In the header file - Remove typedef struct _virIdentity virIdentity - Add #define VIR_TYPE_IDENTITY virIdentity_get_type () G_DECLARE_FINAL_TYPE (virIdentity, vir_identity, VIR, IDENTITY, GObject); Which provides the typedef we just removed, and class declaration boilerplate and various other constants/macros. In the source file - Change 'virObject parent' to 'GObject parent' in the struct - Remove the virClass variable and its initializing call - Add G_DEFINE_TYPE(virIdentity, vir_identity, G_TYPE_OBJECT) which declares the instance & class constructor functions - Add an impl of the instance & class constructors wiring up the finalize method to point to our dispose impl In all files - Replace VIR_AUTOUNREF(virIdentityPtr) with g_autoptr(virIdentity) - Replace virObjectRef/Unref with g_object_ref/unref. Note the latter functions do *NOT* accept a NULL object where as libvirt's do. If you replace g_object_unref with g_clear_object it is NULL safe, but also clears the pointer.
