We want to establish a mapping between option name and option table,
then we can search related option table by option name.
This patch makes all the member name of QemuOptsList to match with
actual command-line spelling(option name).
[ Important Note ]
The QemuOptsList member name values are ABI, changing them can break
existing -readconfig configuration files.
This patch changes:
from to introduced in
acpi acpitable 0c764a9 v1.5.0
boot-opts boot 3d3b830 v1.0
smp-opts smp 12b7f57 v1.6.0
All three have calcified into ABI already.
I have updated the release note of 2.0
