Andrew Bartlett f607197054 r1498: (merge from 3.0) ...

Rework our random number generation system.

On systems with /dev/urandom, this avoids a change to secrets.tdb for every fork().

For other systems, we now only re-seed after a fork, and on startup.
No need to do it per-operation.  This removes the 'need_reseed'
parameter from generate_random_buffer().

This also requires that we start the secrets subsystem, as that is
where the reseed value is stored, for systems without /dev/urandom.

In order to aviod identical streams in forked children, the random
state is re-initialised after the fork(), at the same point were we do
that to the tdbs.
