libretroadmin bdc398d79f - Safer code - use strlcpy where possible instead of manual character 
assignments for strings longer than 2 chars
- Use strlcpy concatenation instead of strlcat
- Make sure that what remains of iteration of the '_len' variable
for manual char assignment
is done in a safer way so mistakes are less possible
