Victor Sun db690e0967 HV: enable multiboot module string as kernel bootargs
Previously the VM kernel bootargs for pre-launched VMs and direct boot mode
of SOS VM are built-in hypervisor binary so end users have no way to change
it. Now we provide another option that the multiboot module string could be
used as bootargs also. This would bring convenience to end users when they
use GRUB as bootloader because the bootargs could be configurable in GRUB
menu.

The usage is if there is any string follows configured kernel_mod_tag in
module string, the string will be used as new kernel bootargs instead of
built-in kernel bootargs. If there is no string follows kernel_mod_tag,
then the built-in bootargs will be the default kernel bootargs.

Please note kernel_mod_tag must be the first word in module string in any
case, it is used to specify the module for which VM.

Victor Sun 47d20f37e1 HV: replace merge_cmdline api with strncat_s
Add a standard string api strncat_s() to replace merge_cmdline() to make code
more readable.

Another change is that the multiboot cmdline will be appended to the end of
configured SOS bootargs instead of the beginning, this would enable a feature
that some kernel cmdline paramter items could be overriden by multiboot cmdline
since the later one would win if same parameters configured in kernel cmdline.

Victor Sun bad12039c6 HV: rewrite strncpy_s to be iso c11 compliant
Per C11 standard (ISO/IEC 9899:2011): K.3.7.1.4

1. Copying shall not take place between objects that overlap;
2. If there is a runtime-constraint violation, the strncpy_s function sets
   s1[0] to '\0\;
3. The strncpy_s function returns zero if there was no runtime-constraint
   violation. Otherwise, a nonzero value is returned.
4. The function is implemented with memcpy_s() because the runtime-constraint
   detection is almost same.

Junjun Shan eb8c4fb0d5 hv:Fix Implict conversion:actual to formal param
MISRAC has requirement about implict conversion: actual to formal
param. This patch is used to fix part of these violations.

1.Add a new structure seg_desc_vmcs to hold the VMCS field address of
segment selector to clean up seg_desc structure.

2.Add the definition of maximum MSI entry and the relevant judgement.

3.The violations in shell.c, logmsg.c will be fixed in other series of
patches with modification of function snprintf(), vsnprintf() and other
related usages.

v1->v2:
  *Move the definition of struct seg_desc_vmcs from instr_emul.h to
   instr_emul.c.
  *Modify the formal parameter type in function definition from uint8_t
   to char instead of using cast.
  *Drop the const declaration for char data in formal parameter.

v2->v3:
  *update the data missing conversion.
  *change type of internal parameter len to avoid casting in npklog.c.
  *change the conversion from signed char to unsigned int in
   uart16550_getc() to solve sign-extension.

Junjie Mao e75cca64c8 HV: timer: keep TSC frequency in KHz
This patch represents TSC freqeuency in KHz using a 32-bit unsigned integer.

The conversion macros between ticks and us/ms are changed to inline functions to
enforce the types of the input parameters. Note that us_to_ticks accepts only
uint32_t (~4K us at most) and never overflows.

Results of some unit tests on the conversion functions:

    calibrate_tsc, tsc_khz=1881600
    64us -> ticks: 120422
    64us -> ticks -> us: 63
    511us -> ticks: 961497
    511us -> ticks -> us: 510
    1280000 ticks -> us: 680
    1280000 ticks -> us -> ticks: 1279488
