This doc-patch adds copyright and license information to (hopefully) all
needed files.

This patch adds a very dumb way to override the port and scheme for
RAPI: if the master string doesn't contain a colon, we consider it a
simple hostname specification, and thus prepend ‘https://’ and append
‘:5080’, (the default RAPI port); otherwise, we consider it a fully
specified URL, and don't do any mangling to it.

This allows to use saved RAPI responses in testing, with the “file://”
scheme, or to use another port or non https mode with an actual RAPI
instance.

This patch documents the environment variables in the man pages of hbal
and hn1.

This moves some data from README to the man pages and has other general
improvements.

This patch adds a man page for hscan and updates the README and other
man pages with the latest changes.

This patch adds a new n_mem field to the node objects, and implements
read/save/show support for it. The field is not currently used (except
in the node list) but will be used for checking data consistency and
instance up/down status.

This patch adds a new ‘-’ flag for the node status which denotes offline
nodes.

A new man page and typos fixed in hbal.1.
