Emphasize that users need to be careful with malloc flags versus mbuf
flags.

Revert to using the .Tn POSIX and .Tn ANSI instead of \*[Px] and \*[Ai]
strings; using these strings is unsafe in troff mode, as they include a

comments since the exemption is intended to handle a particularly

The closing comment is required only for long conditionally defined
code sections, with the exception of lint cases. Attempt to document
also the logic for using '!' before the SOMETIMESSOMETHGINGHERE.
The goal of these comments is to make complex cases more

One bug fixed: Use getmicrouptime() to trigger reseeds so that we
cannot be tricked by a clock being stepped backwards.
Express parameters in natural units and with natural names.
Don't use struct timeval more than we need to.
Various stylistic and readability polishing.
Introduce arc4rand(void *ptr, u_int len, int reseed) function which
returns a stream of pseudo-random bytes, observing the automatic
reseed criteria as well as allowing forced reseeds.
Rewrite arc4random() in terms of arc4rand().
