MTRR support on x86, part 2 (Carl-Daniel Hailfinger)

Load and save MTRR state together with machine state.

Add support for the MTRRcap MSR which is used by the latest Bochs BIOS
and some operating systems.

Fix a typo in ext2_feature_name.

With this patch, MTRR emulation should be good enough to not trigger any
sanity checks in well behaved BIOS/kernel code.
Some corner cases for BIOS/firmware usage remain to be implemented, but
that can be deferred to another patch.
Also, MTRR accesses on hardware not supporting MTRRs should cause #GP.
That can be enforced by another patch as well.
