[ANN] kgio 2.11.3 - deprecated project moves off deprecated TLD

[Eric Wong]

This is a legacy project, do not use it for new projects.  Ruby
2.3 and later should make this obsolete.  kgio provides
non-blocking I/O methods for Ruby without raising exceptions on
EAGAIN and EINPROGRESS.

Note: I do not recommend using kgio for future applications, Ruby 2.x
has a lot of the functionality of kgio and Ruby 2.3+ has even more.

Changes:

    Some doc and warning fixes for newer Rubies.

    We're no longer on bogomips.org since it's due
    for expiry and I can't pay extortionists for a .org, so
    s/bogomips.org/yhbt.net/ for now, and be prepared to move again
    when extortionists move onto the .net TLD.

          pkg.mk: use --local to "gem install"
          pkg.mk: use dark216 theme for Earth Day 2019
          test: fix warnings with RUBYOPT=-w
          tests: fix unused variable warnings from newer Rubies
          test_connect_fd_leak: do not close socket if non-existent
          test_syssend: avoid warning on cleanup
          build: remove olddoc from the gemspec
          doc: remove private email and outdated gmane archives
          doc: move from bogomips.org/kgio to yhbt.net/kgio

Again, using kgio for new projects is strongly discouraged.
Use Ruby 2.3+ instead.
