Starting from automake 1.2 there is parallel test harness, that redirects all
output to some log, which serial-test doesn't do.
So in case of new runner we can get no output for 10 minutes, for example on my
desktop:
$ time make verify VERBOSE=1
PASS: test/test-script.sh

And this means that this will fail on travis-ci, since it has timeout for 10
minutes. Sure we can use `travis wait 60` instead, but I think that it is
better to fix this by writing result to output, instead of hacking around, so
let's use serial-tests instead of parallel always.
And now it works on travis-ci under linux because it has automake 1.11 while
osx has at least 1.12.

CI:
https://travis-ci.org/azat/libevent/jobs/129171497 # ok on linux

This approach should let Make work better, let libevent build faster
(especially when using a parallelized build), and basically make the
Makefiles easier to maintain.
See http://miller.emu.id.au/pmiller/books/rmch/ for more info on why
you'd want to do this.
This is due to an idea from Zack Weinberg; the patch is my own.
This approach should make the creation of the file more atomic, to
fix a bug reported by Dinh.
This patch has one change from Zack's original version: it avoids
$<, since Dave Hart tells me he thinks that's not so portable.

Sufficiently recent kqueue implementations have an EVFILT_USER filter
that we can use to wake up an event base from another thread. When
it's supported, we now use this mechanism rather than our old
(pipe-based) mechanism. This should save some time and complications
on newer OSX and freebsds.
