* Implement --enable-linuxkm-lkcapi-register=stdrng and =stdrng-default,
LINUXKM_LKCAPI_REGISTER_HASH_DRBG, and
LINUXKM_LKCAPI_REGISTER_HASH_DRBG_DEFAULT. With "_DEFAULT", the DRBG is
installed as the systemwide default stdrng, necessitating
deregister-on-command, described below. Note that get_random_bytes() and the
associated /dev/random and /dev/urandom do not use the default stdrng, and
their back end cannot currently be replaced by a module.
* Add control nodes /sys/module/libwolfssl/install_algs and
/sys/module/libwolfssl/deinstall_algs.
* Add configure option --enable-linuxkm-lkcapi-register=sysfs-nodes-only, and
macro LINUXKM_LKCAPI_REGISTER_ONLY_ON_COMMAND, to inhibit registration at
module load time.
In configure.ac ENABLED_LINUXKM_LKCAPI_REGISTER setup, don't define
WOLFSSL_DH_GEN_PUB in old FIPS, but do define it for =all.
