Changes between 1.0.1 and 1.1.0 [xx XXX xxxx]
*) Add FIPS_{rsa,dsa,ecdsa}_{sign,verify} functions which digest and
sign or verify all in one operation.
[Steve Henson]
*) Add fips_algvs: a multicall fips utility incorporaing all the algorithm
test programs and fips_test_suite. Includes functionality to parse
the minimal script output of fipsalgest.pl directly.
[Steve Henson]
*) Add authorisation parameter to FIPS_module_mode_set().
