tfd is one data field of FIS for AHCI, it is unacceptable if it is
random value, could cause AHCI data transport failure.
Acturally there is no chance the switch statement has the value other
than 0~3, since there is only 2 bit to deduce.
Add the initial value for tfd as ATA_S_ERROR, which is checked by
function ahci_write_fis_d2h afterwards, so guest driver could handle it well.

When the virtio-XXX pci devices fall back to legacy PCI intx,
the pci_irq_assert is called to inject the interrupt and then
the pci_irq_deassert is used to mark the completion of PCI interrupt.
Currently the HV vIOAPIC uses the pin_state for the interrupt injection
of legacy PCI intx. In such case it will fail to inject the PCI legacy
intx and the guest system fails to be booted when adding the boot option
of "pci=nomsi".
PCI legacy INTx usually use active low level trigger mode as it is Open-Drain
state and allows multitple interrupt signals to share a single line.
https://wiki.osdev.org/PCI_Local_Bus_Signals
In such case DM needs to set the correct state for the PCI device so that the
HV vIOAPIC can help to inject the PCI legacy intx.
BTW: When the MSI/MSIX is used for PCI device, it uses another mechanism
to inject the interrupt. It is harmless to configure the initial state.

'mevent_lmutex' is initialized as default type,
while attempting to recursively lock on this
kind of mutext results in undefined behaviour.
Recursively lock on 'mevent_lmutex' can be detected
in mevent thread when user tries to trigger system
reset from user VM, in this case, user VM reboot hang.
The backtrace for this issue:
#1 in mevent_qlock () at core/mevent.c:93
#2 in mevent_delete_even at core/mevent.c:357
===>Recursively LOCK
#3 in mevent_delete_close at core/mevent.c:387

core/mevent.c:348 ===> 1st LOCK
#10 in mevent_dispatch () at core/mevent.c:472
#11 in main at core/main.c:1110
So the root cause is:
mevent_mutex lock is recursively locked by mevent thread
itself (#9 for this first lock and #2 for recursively lock),
which is not allowed for mutex with default attribute.
This patch changes the mutex type of 'mevent_lmutex'
from default to "PTHREAD_MUTEX_RECURSIVE", because
recrusively lock shall be allowed as user of mevent
may call mevent functions (where mutex lock maybe required)
in teardown callbacks.

The socket module is to provide interfaces below, the unix domain
socket can be created by command monitor for the communication
between DM instance and libvirt daemon or kata container:
init_socket: allocate a new socket instance according to socket path
deinit_socket: free a socket instance
open_socket: open one unix domain socket server, initialize a
socket, create one thread to listen to client, another thread to
poll message from client.
close_socket: close one unix domain socket server
find_socket_client: find socket client instance according to fd
write_socket_char: send message through unix domain socket server

By default, pCPU is allowed to request software SRAM buffer
from given region in TCC buffer driver only if this pCPU is
set in the target region's CPU affinity configuration.
This check shall be disabled for software SRAM virtualization
usage in ACRN service VM, because software SRAM buffers are
requested by ACRN DM on behalf of user VM, but ACRN DM and
user VM may run on different CPUs while the target software
SRAM region may be configured only for pCPUs that user VM runs on.
This patch turns off such affinity check in TCC driver when
initializing vSSRAM for user VM.

This patch is to eliminate kernel error msgs:
'ACPI Error: AE_NOT_FOUND, Evaluating _PSS'
This is caused by missing of _PSS table in guest ACPI. It would
happen when pstate is not injected to the guest.
Kernel ACPI pstate driver first probes
_PPC(performance capabilites) and _PCT(performance control)
in ACPI. If they exist, then it loads the _PSS(performance state).
If _PPC/_PCT are presented while _PSS is missing, it prints
the error msg.
In acrn-dm, _PPC/_PCT are hard-coded to all vCPUs, while _PSS
are constructed with the pCPUs' pstate data. This is base on
assumption that all VMs can have pstate.
Now the pstate is given to VM only when the VM is not sharing
any CPU(and no RTVM is setup in the scenario).
When the VM doesn't have pstate, the hypercall will return px_cnt=0,
and the _PSS is not constructed. In this case, _PPC/PCT should not
be injected, too.

The UUID has several usages before:
1, For HV to identify the static VM configuration of post-launched VM.
2, Seed virtualization.
3, Slightly prevent launching malicous VM from SOS as lack of secure
boot.
The UUID is confused to user, user don't understand what it is. And user
don't know where to get/apply the UUID. The worst experience is user
can't launch any VMs w/o re-compile the hv. Everything needs to be
static decided in building phase.
Now we decide to remove UUID and split each usage. For 1st usage, use
vmname as the identifier of static VM configuration. For 2nd one, we
will use --vseed as the new parameter. For 3rd one, will pretect by
SOS's dm-verity.
This patch will remove the UUID parameter and support 1st&3rd usages
from DM part. For 2nd usage, another patch will be submitted later.
