From 8ff84e7f181aa0f64b3b6178d9ac808c61f5bec8 Mon Sep 17 00:00:00 2001
From: Miroslav Rezanina <mrezanin@redhat.com>

Subject: Initial redhat build
This patch introduces redhat build structure in redhat subdirectory. In addition,
several issues are fixed in QEMU tree:
- Change of app name for sasl_server_init in VNC code from qemu to qemu-kvm
- As we use qemu-kvm as name in all places, this is updated to be consistent
- Man page renamed from qemu to qemu-kvm
- man page is installed using make install so we have to fix it in qemu tree
- Use "/share/qemu-kvm" as SHARE_SUFFIX
- We reconfigured our share to qemu-kvm to be consistent with used name
This rebase includes changes up to qemu-kvm-2.12.0-47.el8
Rebase notes (3.1.0):
- added new configure options
Merged patches (3.1.0):
- 01f0c9f RHEL8: Add disable configure options to qemu spec file
- Spec file cleanups
