Implement generalised RSA public exponents for verified boot
Remove the verified boot limitation that only allows a single
RSA public exponent of 65537 (F4). This change allows use with
existing PKI infrastructure and has been tested with HSM-based
PKI.
Change the configuration OF tree format to store the RSA public
exponent as a 64 bit integer and implement backward compatibility
for verified boot configuration trees without this extra field.
Parameterise vboot_test.sh to test different public exponents.
Mathematics and other hard work by Andrew Bott.
Tested with the following public exponents: 3, 5, 17, 257, 39981,
50457, 65537 and 4294967297.
