This patch moves get_bzimage_kernel_load_addr() from init_vm_sw_load() to
vm_sw_loader() stage so will set kernel load address of bzImage type kernel
in vm_bzimage_loader() in vm_load.c.

In load_sw_modules() implementation, we always assuming the guest kernel
module has one load address and then the whole kernel image would be loaded
to guest space from its load address. This is not true when guest kernel
has multiple load addresses like ELF format kernel image.
This patch removes load_sw_modules() API, and the loading method of each
format of kernel image could be specified in prepare_loading_xxximage() API.

As the previous commit said the kernel load address should be moved
from init_vm_sw_load() to vm_sw_loader() stage. This patch refines

Currently the guest kernel load address and ramdisk load address are
initialized during init_vm_sw_load() stage, this is meaningless when
guest kernel has multiple segments with different loading addresses.
In that case, the kernel load addresses should be parsed and loaded
in vm_sw_loader() stage, the ramdisk load address should be set in
that stage also because it is depended on kernel load address.
This patch refines the API of get_initrd_load_addr() which will set
proper initrd load address of bzImage type kernel for later use.

In some scenarios (e.g., nested) where lapic-pt is enabled for a vcpu
running on a pcpu hosting console timer, the hv console will be
inaccessible.
This patch adds the console callback to every VM-exit event so that the
console can still be somewhat functional under such circumstance.
Since this is VM-exit driven, the VM-exit/second can be low in certain
cases (e.g., idle or running stress workload). In extreme cases where
the guest panics/hangs, there will be no VM-exits at all.
In most cases, the shell is laggy but functional (probably enough for
debugging purpose).

For an atomic operation using bus locking, it would generate LOCK# bus
signal, if it has Non-WB memory operand. This is an UC lock. It will
ruin the RT behavior of the system.
If MSR_IA32_CORE_CAPABILITIES[bit4] is 1, then CPU can trigger #GP
for instructions which cause UC lock. This feature is controlled by
MSR_TEST_CTL[bit28].
This patch enables #GP for guest UC lock.

When ACRN uses decode_instruction to emulate split-lock/uc-lock
instruction, It is actually a try-decode to see if it is XCHG.
If the instruction is XCHG instruction, ACRN must emulate it
(inject #PF if it is triggered) with peer VCPUs paused, and advance
the guest IP. If the instruction is a LOCK prefixed instruction
with accessing the UC memory, ACRN Halted the peer VCPUs, and
advance the IP to skip the LOCK prefix, and then let the VCPU
Executes one instruction by enabling IRQ Windows vm-exit. For
other cases, ACRN injects the exception back to VCPU without
emulating it.
So change the API to decode_instruction(vcpu, bool full_decode),
when full_decode is true, the API does same thing as before. When
full_decode is false, the different is if decode_instruction() meet unknown
instruction, will keep return = -1 and do not inject #UD. We can use
this to distinguish that an #UD has been skipped, and need inject #AC/#GP back.
