- Reduce quantity of ifdef code, in preparation for ssh_rand_conf
- Always seed from system calls, even when doing PRNGd seeding
- Tidy and comment #define knobs
- Remove unused facility for multiple runs through command list
- KNF, cleanup, update copyright

- (djm) Rework entropy code. If the OpenSSL PRNG is has not been
internally seeded, execute a subprogram "ssh-rand-helper" to obtain
some entropy for us. Rewrite the old in-process entropy collecter as
an example ssh-rand-helper.
- (djm) Always perform ssh_prng_cmds path lookups in configure, even if
we don't end up using ssh_prng_cmds (so we always get a valid file)
