It is preferred to state the absence of a return value explicitly in the
doxygen-stile comments. Currently there are different styles of doing this,
including:
@return None
@return NULL
@return void
@return N/A
This patch unifies the above with `@return None`.

Now if the vmexit reason is virtulized EOI for level triggered
interrupts, HV will loop all the ptdev entries, it is time-consuming,
this patch add vpin to ptdev entry mapping for vpic and vioapic
when add intx entry for a vm,it can use the ptdev entry directly
according to the mapping for vpin and ptdev entry when EOI vmexit.
v3-->v4:
-- add check vpin in remove_intx_remapping
-- move check vpin from ptdev_add_intx_remapping to add_intx_remapping

For data structure types "struct vm", its name is identical
with variable name in the same scope. This is a MISRA C violation.
Naming convention rule:If the data structure type is used by multi
modules, its corresponding logic resource is exposed to external
components (such as SOS, UOS), and its name meaning is simplistic
(such as vcpu, vm), its name needs prefix "acrn_".
The following udpates are made:
struct vm *vm-->struct acrn_vm *vm

There are chances that names with leading underscore declared by
developers are conflict with the ones reserved for the compiler.
What this patch does:
- rename these functions/variables/macros starting with
underscore to avoid such unintentational mistakes.
- remove gpr.h without any contents

MISRA-C requires that each function defined and declared shall be called
or referenced in code analyzed.
In some cases, we would like to keep the non-called functions for code
completeness, such as
vcpu_inject_extint/vcpu_inject_nmi/vcpu_inject_gp/vcpu_inject_pf
/vcpu_inject_ud/vcpu_inject_ac/vcpu_inject_ss.
This pacth removes some functions that are independent and are not
called in our code base.

There are many naming violations detected by static analysis
tool. Data structure type name is the same as variable name.
According to naming convention rules, If the data structure
type is used by multi modules and its name meaning is
simplistic (such as vcpu, vm), its name needs prefix "acrn_".
Rename struct vpic as struct acrn_vpic.
Replace regular expression:s/struct vpic\([ ),;\t\*]\+\)/struct acrn_vpic\1

Currently irq and vector numbers are used inconsistently.
* Sometimes vector or irq ids is used in bit operations, indicating
that they should be unsigned (which is required by MISRA C).
* At the same time we use -1 to indicate an unknown irq (in
common_register_handler()) or unavailable irq (in
alloc_irq()). Also (irq < 0) or (vector < 0) are used for error
checking. These indicate that irq or vector ids should be signed.
This patch converts irq and vector numbers to unsigned 32-bit integers, and
replace the previous -1 with IRQ_INVALID or VECTOR_INVALID. The branch
conditions are updated accordingly.
