## New functions:
+ implement `_exit`/`_Exit`.
+ implement `atexit`.
+ implement `abort`.
`abort` write `Aborted pid: %d` to debug board
## Changes:
### call `exit` after main.
Just calling `exit`
### `exit` write exit code
If exit code isn't 0 `exit` will write exit code to debug board.
### use `con_exit(0)`
use
```c
con_exit(0)
```
instead of
```c
con_exit(status);
```
[from console.obj readme](310999dcc4/programs/develop/libraries/console_coff/console_en.txt (L15)).
I think the console window shouldn't be so dependent on the exit code. It's must only always close or always stay on screen
### `exit` writing exit code to debug board
Since the exit code is not used anywhere right now, I think it's better to just show it on the debug board.
for auto rebuild `crt0.o` need #339
from #311
