Proposed patch to add -readconfig/-writeconfig command line options

This is the patch to include -readconfig and -writeconfig command line
options to the QEMU man page. Those commands are useful when using
many devices and/or command line arguments in general to save space
in the QEMU command line.

Reproduce on qemu-kvm-, and verified on qemu-kvm-
So this bug was fixed.

Comment 7 mazhang 2012-10-25 11:59:10 UTC
Verified this issue on:
kernel 2.6.32-335.el6.x86_64

The man page output is in follow:
#man qemu-kvm | grep -A4 writeconfig
       <-writeconfig file>
           Write device configuration to file. The file can be either filename
           to save command line and device configuration into file or dash
           "-") character to print the output to stdout. This can be later
           used as input file for "-readconfig" option.

# man qemu-kvm | grep -A4 readconfig
       <-readconfig file>
           Read device configuration from file. This approach is useful when
           you want to spawn QEMU process with many command line options but
           you don’t want to exceed the command line character limit.
