rng-tools: new package for rng-tools (rngd) version 5

random number generator daemon - seed kernel random from hwrng

This daemon feeds data from a random number generator to the kernel's
random number entropy pool, after first checking the data to ensure
that it is properly random.

By default, a hardware rng at /dev/hwrng is used as entropy source.

This daemon is part of the rng-tools, which can be found at
    http://sourceforge.net/projects/gkernel/
    git://git.kernel.org/pub/scm/utils/kernel/rng-tools/rng-tools.git
