Remove some unreached/duplicated code.
Add error checking for `atoi()` calls.
About `isdigit()` and similar functions. The warning reported is:
```
Negative Character Value help
isdigit() is invoked here with an argument of signed type char, but only
has defined behavior for int arguments that are either representable
as unsigned char or equal to the value of macro EOF(-1).
Casting the argument to unsigned char will avoid the undefined behavior.
In a number of libc implementations, isdigit() is implemented using lookup
tables (arrays): passing in a negative value can result in a read underrun.
```
Switching to our macros fix that.
Add a check to `check_symbols.sh` to avoid using the original functions
from libc.

Some BSD APIs called in example/ return `struct bpf_timeval`, where nDPI
APIs expect `struct timeval`. These two structs, besides having
a different name, share the exact same set of fields.
