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.
