arc4random.c: In the incredibly unbelievable circumstance where
_rs_init() fails to allocate pages, don't call abort() because of
corefile data leakage concerns, but simply _exit(). The reasoning
is _rs_init() will only fail if someone finds a way to apply
specific pressure against this failure point, for the purpose of
leaking information into a core which they can read. We don't
need a corefile in this instance to debug that. So take this
"lever" away from whoever in the future wants to do that.
arc4random.3: reference random(4)
arc4random_uniform.c: include stdint.h over sys/types.h

libkern in .PATH has too many filename conflicts with libc and my -DNO_CLEAN
tinderbox didn't catch that ahead of time. Mea culpa.
libkern: Bring in arc4random_uniform(9) from libc2019-04-19T20:05:47ZConrad Meyercem@FreeBSD.org2019-04-19T20:05:47Zurn:sha1:7deb4b1964834c479406cab511de339a6cc0088e
It is a useful arc4random wrapper in the kernel for much the same reasons as
in userspace. Move the source to libkern (because kernel build is
restricted to sys/, but userspace can include any file it likes) and build
kernel and libc versions from the same source file.
Copy the documentation from arc4random_uniform(3) to the section 9 page.
While here, add missing arc4random_buf(9) symlink.
