ObsoleteFiles.inc:
Remove manual pages for arc4random_addrandom(3) and
arc4random_stir(3).
contrib/ntp/lib/isc/random.c:
contrib/ntp/sntp/libevent/evutil_rand.c:
Eliminate in-tree usage of arc4random_addrandom().
crypto/heimdal/lib/roken/rand.c:
crypto/openssh/config.h:
Eliminate in-tree usage of arc4random_stir().
include/stdlib.h:
Remove arc4random_stir() and arc4random_addrandom() prototypes,
provide temporary shims for transistion period.
lib/libc/gen/Makefile.inc:
Hook arc4random-compat.c to build, add hint for Chacha20 source for
kernel, and remove arc4random_addrandom(3) and arc4random_stir(3)
links.
lib/libc/gen/arc4random.c:
Adopt OpenBSD arc4random.c,v 1.54 with bare minimum changes, use the
sys/crypto/chacha20 implementation of keystream.
lib/libc/gen/Symbol.map:
Remove arc4random_stir and arc4random_addrandom interfaces.
lib/libc/gen/arc4random.h:
Adopt OpenBSD arc4random.h,v 1.4 but provide _ARC4_LOCK of our own.
lib/libc/gen/arc4random.3:
Adopt OpenBSD arc4random.3,v 1.35 but keep FreeBSD r114444 and
r118247.
lib/libc/gen/arc4random-compat.c:
Compatibility shims for arc4random_stir and arc4random_addrandom
functions to preserve ABI. Log once when called but do nothing
otherwise.
lib/libc/gen/getentropy.c:
lib/libc/include/libc_private.h:
Fold __arc4_sysctl into getentropy.c (renamed to arnd_sysctl).
Remove from libc_private.h as a result.
sys/crypto/chacha20/chacha.c:
sys/crypto/chacha20/chacha.h:
Make it possible to use the kernel implementation in libc.
