07039b8a36 lib_abort.c: Change call to userspace exit() into syscall _exit() 
The POSIX standard dictates that during abnormal termination the functions
registered by atexit() are _not_ called, also flushing the streams is
optional. So in this case, it is perfectly legal / better to call the
kernel system call _exit() instead.

This fixes regression issues caused by removal exit() from the kernel.

df1d7dd480 libc/exit: Purge calls to userspace API exit() from kernel 
Remove calls to the userspace API exit() from the kernel. The problem
with doing such calls is that the exit functions are called with kernel
mode privileges which is a big security no-no.

fa59db8cea Add Hexadecimal parsing for strtof 
solve:
  almost the Hexadecimal string string->float
such as:
  code:float num;
       const char *s= "0x123p32lala";
       char *p;
       num=strtof(s,&p);
       printf("num is %f\n",num);
       printf("str is %s\n",p);
  output:num is 1249835483136.000000
         str is lala

but if the input number is much big;
like:
  code:const char *s2= "0x999999p100";
       num=strtof(s2,&p);
       printf("num is %f\n",num);
       printf("str is %s\n",p);
  corrent : num is 12760587998944832242938906880669384704.000000
  real:     num is 12760587998944800000000000000000000000.000000
it didn't have enough precision
