Before there was some awkward ambiguity between top level
key names and node names. For example a node named 'error'
would be tricky. Address that by allocating a 'databynode'
top level container to clarify the namespace of keys is
nodenames specifically. Use this to simplify code that
tried to workaround the ambiguity.
For certain scenarios (e.g. wcons), having a path to get in and communicate data from the outside.
For starters, have a 'GETWINID' directive for wcons to use to fetch the unambiguous window id
to use for xwininfo tricks. TODO includes concepts from xtcd.pl that enabled things like warr
Some clients have their lives made more convenient by having the
sha512 hash rather than the actual certificate. Prepend with 'sha512$'
to allow for a future where different formats could be specified.
