svn rev #24420: trunk/src/ lib/crypto/ lib/crypto/builtin/ lib/crypto/builtin/sha2/ ...

http://src.mit.edu/fisheye/changelog/krb5/?cs=24420
Commit By: tsitkova
Log Message:
Improves prng code modularity. Introduces fortuna-like prng that can be used in lieu of yarrow. 
Yarrow stays the default prng while fortuna may be engaged during configuration by using "--with-prng-alg=fortuna" flag.
Also, nss crypto backend continues to use its own prng.
