Some minor updates and fixes, mainly to workaround for a
(now-fixed upstream) Linux kernel bug. I doubt anybody
uses this, yet, or ever will at this point...
Changes:
8 changes since 1.17.0 (2019-04-22):
worker: workaround old F_SETPIPE_SZ bug
doc: favor File.read over IO.read to ease review
proxy_pass: document as a public API
doc: include Yahns/ directory on website
extras/try_gzip_static: set "Vary: Accept-Encoding" on gzip
do not sleep if signals are pending
server: workaround Linux v5.5..v5.13 epoll bug
gemspec: allow unicorn 6.x
* homepage: https://yhbt.net/yahns/
* git clone https://yhbt.net/yahns.git

This should prevent missed/delayed wakeups if repeatedly
kill(2)-ed.

It's been a while since I've run the test suite, turns out there
was a Linux kernel bug introduced and fixed which was causing
shutdown timeouts.
A couple of other minor things, too...
