Add HYP API to invalidate all VM TLBs without passing address parameter,
that kvm_tlb_flush_vmid_ipa() uses. Hopefully this is a valid way
to do it. Tests show nothing is broken.
The address parameter is confusing since whole VM is being invalidated.

Add support for initial write protection of guest VM, to later manage dirty
pages. Reduced TLB flushing to one flush after memory region is write protected.
This is based on Erics patch, which applied cleanly. The only patch I found
in the archives was the memory region delete, but still in arm.c.
Revised iteration after initial comments. Still just for ARMv7. I looked
at the ARMv8 code and yes it practically appears to reuse most of
fault handling in ARMv7, I wasn't aware so much code was in common.
But before then want to make sure it's reliable on real hardware.

Remove the if conditional - that will help us avoid
an "else initialize to 0" Also, rearrange operators
for slightly better code.

While initializing emulation context structure, kvm memsets to 0 a
number of fields some of which are redundant since they get set
eventually in x86_decode_insn. Cleanup unnecessary initializations
and remove some fields.
