bad50ed24f libutils: check vsnprintf error 
For encoding errors, this function will return a negative value which
causes problems down the line. Check for an error and return. Also,
integer overflows are guarded.

Test: fuzzer test case

fdbc565dd5 String8: explicit int -> char cast. 
Since tolower/toupper take and return integer arguments, ascii chars in
the extended range will be converted from positive int values to
negative char values. In order to silence an error here, which was added
recently with integer sanitization here, casting explicitly.

fff9d11be5 Fix undefined args access for x86_64. 
From libc manual for vsnprintf:
   The  functions  vprintf(),  vfprintf(), vsprintf(), vsnprintf()
   are equivalent to the functions printf(), fprintf(), sprintf(), snprintf(),
   respectively, except that they are called with a va_list instead of a
   variable number of arguments.  These  functions  do  not  call  the  va_end  macro.
   Because they invoke the va_arg macro, the value of ap is undefined after the call.

We need to allocate/end new va_list for each vsnprintf.
