ACPICA: Add safe versions of common string functions.
This change adds and deploys "safe" versions of strcpy and strcat that ensure that the target buffer does not overflow. These safe functions are only helpful for processing user input and command lines. For most ACPICA code however, the required buffer length is precisely calculated before buffer allocation, so the use of these functions is unnecessary. ACPICA BZ 1043. This change only applies to the ACPICA utilities and the debugger, none of which are not shipped with the kernel yet, so the kernel's behavior remains unchanged after it.
