Closes ticket 26004.

Stop saying in the manual that clients cache ipv4 dns answers from exit
relays. We haven't used them since 0.2.6.3-alpha, and in ticket 24050
we stopped even caching them as of 0.3.2.6-alpha, but we forgot to say
so in the man page.

Fixes bug 26052; bugfix on 0.3.2.6-alpha.

better punctuation and clearer wording

Code movement for the refactoring for ticket 24658 didn't copy the
inclusion of sys/random.h, which is needed to get a prototype for
getentropy() on macOS 10.12 Sierra.  It also didn't copy the inclusion
of sys/syscall.h, which might prevent the getrandom() syscall from
being properly detected.  Move these inclusions.  Bug not in any
released Tor.

Our previous algorithm had a nonzero probability of picking no
events to cancel, which is of course incorrect.  The new code uses
Vitter's good old reservoir sampling "algorithm R" from 1985.

Fixes bug 26008; bugfix on 0.2.6.3-alpha.

This functionality was covered only accidentally by our voting-test
code, and as such wasn't actually tested at all.  The tests that
called it made its coverage nondeterministic, depending on what time
of day you ran the tests.

Closes ticket 26014.
