Bug#235304: apache exits silently without error or deleting /var/run/apache.pid

[Neil Williams <linux@codehelp.co.uk>]

Package: apache
Version: 1.3.29.0.1-5
Severity: grave
Tags: sid
Justification: renders package unusable

After the most recent cron-apt update on testing, apache simply fails to
start but gives no error reports. /var/run/apache.pid is not deleted. No
syntax changes or errors in httpd.conf.

Trying to restart apache complains about existence of the pid file but
again exits silently.

apachectl start appears to show a successful start but ps waux shows no
apache processes.
