In get_option(): don't read past the end of the option buffer.
Also add a small unittest to verify sane behaviour for the above.
The dhcpcd code is not easily refactored into a library, nor is it
entirely possible to include some header files directly since some
structures use C++ reserved keywords ("new") for variable names.
In print_option(): use of snprintf() returns the length that
/would/ have been written. Add checks that the output buffer
is not overrun when printing.
This fixes CVE-2014-7912 and CVE-2014-7913
