[PATCH 4/6] docs/about/removed-features: Document removed HMP commands from QEMU v2.12

[Thomas Huth <thuth@redhat.com>]

These HMP commands had been removed/replaced in QEMU v2.12. Still, some
people might want to update from older versions to the recent QEMU version,
so we should give some recommendations for the replacements in our
documentation.
