This reverts commit 81866147.

Hostname is dot-less. Domain name may contain dots.

When a process is stopped:
- it may not have emitted logs since previous rotation: add "missingok"
  As a direct consequence: stop using logrotate recipe.
- its pid file (if applicable) may be missing: test its non-empty presence
  before calling slapos-kill
Also, stop using slapos.cookbook:logrotate.
Update obvious users (cloudooo, neoppod, erp5, monitor, re6stnet).

This reverts commit 928ee00d.

This causes further regressions when building libavcodec. So revert this
partial fix for now.

0.9.6 fails to build on (at least) gcc 6.3.0, with:

Also, add --disable-static configure option.
Also, reindent configure options.
