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

We disable make check due to issues with some of the tests.

This rebase is based on qemu-kvm-6.2.0-13.el9

+QEMU tracing using systemtap-initscript

+---------------------------------------

+

+You can capture QEMU trace data all the time using systemtap-initscript.  This

+uses SystemTap's flight recorder mode to trace all running guests to a

+fixed-size buffer on the host.  Old trace entries are overwritten by new

+entries when the buffer size wraps.

+

+1. Install the systemtap-initscript package:

+  # yum install systemtap-initscript

+

+2. Install the systemtap scripts and the conf file:

+  # cp /usr/share/qemu-kvm/systemtap/script.d/qemu_kvm.stp /etc/systemtap/script.d/

+  # cp /usr/share/qemu-kvm/systemtap/conf.d/qemu_kvm.conf /etc/systemtap/conf.d/

+

+The set of trace events to enable is given in qemu_kvm.stp.  This SystemTap

+script can be customized to add or remove trace events provided in

+/usr/share/systemtap/tapset/qemu-kvm-simpletrace.stp.

+

+SystemTap customizations can be made to qemu_kvm.conf to control the flight

+recorder buffer size and whether to store traces in memory only or disk too.

+See stap(1) for option documentation.

+

+3. Start the systemtap service.

+　# service systemtap start qemu_kvm

+

+4. Make the service start at boot time.

+　# chkconfig systemtap on

+

+5. Confirm that the service works.

+  # service systemtap status qemu_kvm

+  qemu_kvm is running...

+

+When you want to inspect the trace buffer, perform the following steps:

+

+1. Dump the trace buffer.

+  # staprun -A qemu_kvm >/tmp/trace.log

+

+2. Start the systemtap service because the preceding step stops the service.

+  # service systemtap start qemu_kvm

+

+3. Translate the trace record to readable format.

+  # /usr/share/qemu-kvm/simpletrace.py --no-header /usr/share/qemu-kvm/trace-events /tmp/trace.log
