trans: New random translator.

Previously, the Hurd included a translator providing /dev/random and
/dev/urandom based on a source copy of the random number generator
found in classic GnuPG.

The new random translator is using the SHAKE128 algorithm from the
SHA-3 family as the underlying cryptographic primitive.  Being a
sponge construction, it allows the extraction of arbitrary amounts of
pseudorandom data.  It is continuously fed entropy by hashing system
state that is hard to predict.

* Makefile (prog-subdirs): Remove 'random'.
* NEWS: Update.
* random/Makefile: Delete file.
* random/TODO: Likewise.
* random/gnupg-bithelp.h: Likewise.
* random/gnupg-glue.h: Likewise.
* random/gnupg-random.c: Likewise.
* random/gnupg-random.h: Likewise.
* random/gnupg-rmd.h: Likewise.
* random/gnupg-rmd160.c: Likewise.
* random/random.h: Likewise.
* sutils/MAKEDEV.sh (random): Create node.
(urandom): The new translator is both secure and non-blocking.  Create
a link from urandom to random for compatibility with Linux.
* trans/Makefile (targets): Add 'random'.
* trans/random.c: Move the skeleton of the old random translator here,
but replace the PRNG with SHAKE128.  Remove all dubious attempts of
accounting for entropy.  Do not block ever.
