Previously, msrtool would assume that MSR values should be compared
between stored value in file and current value in hardware which msrtool
was running on. This does not always fit the use case and with this
change msrtool can now compare two sets of MSR values stored in a file.
If only one MSR value is stored in the file, msrtool will behave as
before, and read the second MSR value from hardware.
This change means that msrtool does not always need access to the system
MSR functions so it can now be run as a regular user when using diff
mode with both MSR values stored in the file.

This also introduces a small change in the user interface for immediate
mode (-i). Previously, whitespace could separate high and low words in
an MSR as such:
msrtool -i 4c00000f='f2f100ff 56960004'
That is no longer allowed, a space character now ends the MSR value. Any
other character can still be used as separator however, so the following
syntax still works as expected:
msrtool -i 4c00000f=f2f100ff:56960004

The only actual code change is from
if (.. >= 1) {
}
to
if (.. < 1)
continue
so this is pretty trivial.

msrtool can decode MSRs and print the value of every field in human
readable form. It can also be used to save a set of MSRs to a file,
and at a later time compare the saved values with current values in
hardware.
