[PATCH v2 1/6] docs/about/deprecated: Deprecate the qemu-system-i386 binary

[Thomas Huth <thuth@redhat.com>]

Hardly anybody really requires the i386 binary anymore, since the
qemu-system-x86_64 binary is a proper superset. So let's deprecate
the 32-bit variant now, so that we can finally stop wasting our time
and CI minutes with this.

With regards to 32-bit KVM support in the x86 Linux kernel,
the developers confirmed that they do not need a recent
qemu-system-i386 binary here:

+'''''''''''''''''''''''''''''''''''''''
+
+The ``qemu-system-i386`` binary was mainly useful for running with KVM
+on 32-bit x86 hosts, but most Linux distributions already removed their
+support for 32-bit x86 kernels, so hardly anybody still needs this. The
+``qemu-system-x86_64`` binary is a proper superset and can be used to
+run 32-bit guests by selecting a 32-bit CPU model, including KVM support
+on x86_64 hosts. Thus users are recommended to reconfigure their systems
+to use the ``qemu-system-x86_64`` binary instead.
