The coding guideline rule C-TY-12 requires that 'all type conversions shall

shall be avoided.
This patch either adds explicit type casts or adjust local variable types
to make sure that Booleans, signed and unsigned integers are not used
mixedly.

The coding guideline rule C-TY-02 requires that 'the operands of bit
operations shall be unsigned'. This patch adds explicit casts or literal
suffixes to make explicit the type of values involved in bit operations.
Explicit casts to widen integers before shift operations are also
introduced to make explicit that the variables are expanded BEFORE it is
shifted (which is already so in C99 but implicitly).

This patch fixes the following warnings detected by the LLVM/Clang
compiler:
1. Unused static functions in C sources, which are fixed by explicitly
tagging them with __unused
2. Duplicated parentheses around branch conditions
3. Assigning 64-bit constants to 32-bit variables, which is fixed by
promoting the variables to uint64_t
4. Using { '\0' } to zero-fill an array, which is fixed by replacing it
with { 0 }
5. Taking a bit out of a variable using && (which should be & instead)
Most changes do not have a semantic impact, except item 5 which is probably
a real code issue.

when we add two or more virtio block devices and rename them for a VM
in launch xml files, then generate launch scripts through the UI.
After ensuring the devices names are different, we repeat these operations
continuously. Finally we will get the duplicate PT_SLOT value 30 for
different virtio block devices in a launch script. This is wrong.
As a workaround, we reassign PT_SLOT variate to reset it after the launch
script is generated every time.

In lock instruction emulation, we use vcpu_make_request and
signal_event pairs to shoot down/release other vcpus.
However, vcpu_make_request is async and does not guarantee an execution
of wait_event on target vcpu, and we want wait_event to be consistent
with signal_event.
Consider following scenarios:
1, When target vcpu's state has not yet turned to VCPU_RUNNING,
vcpu_make_request on ACRN_REQUEST_SPLIT_LOCK does not make sense, and will
not result in wait_event.
2, When target vcpu is already requested on ACRN_REQUEST_SPLIT_LOCK (i.e., the
corresponding bit in pending_req is set) but not yet handled,
the vcpu_make_request call does not result in wait_event as 1 bit is not
enough to cache multiple requests.
This patch tries to add checks in vcpu_kick_lock_instr_emulation and
vcpu_complete_lock_instr_emulation to resolve these issues.
