[RFC PATCH v3 0/4] Real mode interrupt injection

This patch introduces real mode interrupt injection for VMX.
It currently invokes the x86 emulator to emulate interrupts
instead of manually setting VMX controls.

Needless to say, this is not meant for merging in its current state.
The emulator still needs some more work to get this completely operational.

Mohammed Gamal (4):
x86 emulator: Expose emulate_int_real()
x86: Separate emulation context initialization in a separate function
x86: Add kvm_inject_realmode_interrupt() wrapper
VMX: Emulated real mode interrupt injection

Changes since v2:
- Refactored emulation context initialization code
- Commit eip value from the decode cache to the emulation context in x86.c rather than the emulator
- Add kvm_* prefix to inject_realmode_interrupt() global symbol for consistency
