document pcmk-follow-daemon
Convenient way to follow into particular daemon when starting debugging
from the master control process of pacemaker (pacemakerd).
For "pacemaker-" prefixed daemons, this very prefix is not needed.

Examples: pcmk-follow-daemon "controld"

document pcmk-xmlnode2file
Convenient way to dump an XML element to specified file, or a temporary file
when it's not.
Synopsis: pcmk-xmlnode2file XMLNODEPTR-EXPR [FILE-NAME]
Examples: pcmk-xmlnode2file node "debug-dump.xml"

Convenient way to shut pacemaker down as a whole, no matter from
which process, parent or child, and safely(!).
