This change affects DHCP servers and D2.

Changes include documenting the constants used for selection of parameters
to be reported by getConfigSummary and a todo.

Removed the IfaceMgr.detectIfaces_linux test as it is covered in the
IfaceMgr.detectIfaces test already.

The original version of this test incorrectly matched the names of the
interfaces detected by the IfaceMgr and those detected by the unit test.
As a result, the interfaces with similar names (e.g. virbr0 and virbr0-nic)
where compared for the equality of indexes, addresses and flags.

This was noticed by wlodek.
The docbook source was not added to the DOCBOOK list, but
the master file brings it in.
This breaks the document generation from the tarball (which was
missing the file).

I didn't get it reviewed, but I tested it and it is a one-line
trivial change.

Note that my distcheck automated builder has document generation
not enabled so this was not seen. We need to make sure the
document generation is automated using a "dist" tarball.
(My other automated document generation is from the git repo.)
