msrtool: Add endptr to str2msr() showing how many characters were parsed
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
