this patch save native lapic configuration and restore it to vm0's vlapic
before its running, then doing hpet timer interrupt injection through vlapic
interface -- this will not mess up vlapic and we can see hpet
timer interrupt coming continuously.

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.

If you build for a platform (e.g. uefi) and right after that for
another platform ('sbl'), the new build will fail and a version.h
file is left in the tree (bsp/uefi/include/bsp/version.h or
bsp/sbl/include/bsp/version.h depending on the order you built one
after the other). This commit makes git ignore any of those in case
it is there. Note that 'make clean' with the corresponding
PLATFORM variable will clean this file.

According to the explaination for pref_address
in Documentation/x86/boot.txt, a relocating bootloader
should attempt to load kernel at pref_address if possible.
But due to a non-relocatable kernel will unconditionally
move itself and to run at perf address, no need to copy
kernel to perf_address by bootloader.

It is possible that the vm-entry fails in vmresume instr under some scenarios.
It will pass to next instruction following vmresume. In such case it will call
the vmlaunch again.

Add 'CPU_PAGE_MASK' used for calculate address,
Change IA32E_REF_MASK from 0x7ffffffffffff000 to 0x000ffffffffff000
for MMU/EPT entry, bit62:52(ignore) bit63(VE/XD)
if we want to obtain the address from the MMU/EPT entry,need to clear
bit63:52 by IA32E_REF_MASK

This patch is prepared for enabling secure world feature.
this api will create new eptp for secure world, whose PDPT
entries are copied form normal world,the PML4/PDPT for secure
world are separated from Normal World, PD/PT are shared in the
Secure World's EPT and Normal World's EPT.Secure world can
access Normal World's memory, but Normal World can not access
Secure World's memory
This function implemented：
-- Unmap specific memory from guest ept mapping
-- Copy PDPT from Normal world to Secure world
-- Map specific memory for Secure world
-- Unmap specific memory from SOS ept mapping

Replace ASSERT in lib functions with error message print and return a
value indicating error to allow the caller of lib functions to handle
the error.

"-O2 -D_FORTIFY_SOURCE=2":
GCC C-Compiler can analyze the source code to be compiled and detect
certain insecure sections, that might create a security problem. The
compiler will replace the insecure function calls with special hardened
code that will perform extra runtime checks while the process is
executed.
"-Wformat -Wformat-security":
It warns about calls to "printf" and "scanf" functions where the format
string is not a string literal and there are no format arguments, as in
"printf (foo);". This may be a security hole if the format string came
from untrusted input and contains %n.
