- inject exception based on exception_info
- inject exception according to priority
- for previous not injected vector - idt_vectoring_info, here only take
care about types for SW exception & external interrupt, the HW exception
& NMI will be taken care by vmexit_handler in the following commit "correct
idt_vectoring_info handling"

the pending_intr is not only serving for interrupt but also for different
request including TLB & TMR updating, so change the function & variants
name accordingly.

According to the comments in hypervisor:
" This file includes config header file "bsp_cfg.h" and other
hypervisor used header files.
It should be included in all the source files."
this patch includes all common header files in hypervisor.h
then removes other redundant inclusions

- According to Intel SDM 24.9.2,Vol3, should check the
validity of "VM-exit interruption information" before
extracting the vector of interrupt.

1. exception vector and other information
can be extracted from 'VM-Exit Interrupt-Information'
field of VMCS only if bit31 (Valid) is set.
-Intel SDM 24.9.2, Vol3
2. Rename 'exit-interrupt_info' to 'idt_vectoring_info'
in 'struct vcpu_arch', which is consistent with
SDM 24.9.3, Vol3
3. 'IDT-vectoring information' in VMCS is 32bit
-Intel SDM 24.9.3, Vol3
Update the type of 'idt_vectoring_info' in
'struct vcpu_arch'from 'uint32_t' to 'uint64_t'.

we added uefi stub for hv, and want vm0 continue running under uefi env to
boot other uefi payload (osloader or bzImage).
during this, the uefi timer irq need be handled elegantly.
there are 3 types for uefi timer:
1. 8254 based on IRQ0 of PIC
2. HPET based on IOAPIC
3. HPET based on MSI
currently, we only support type 3 (HPET+MSI). But we are following a
in-correct flow to handle this timer interrupt:
- we set VMX_ENTRY_INT_INFO_FIELD directly if a timer interrupt happened
before vcpu launching, this will make its vlapic mess up, which finally
cause hpet timer stop.
this patch remove this in-correct approach, the new approach patch will
be followed by next patch.
