6200432d85 KCC: remove essentially dead code
As the removed comment noted, the logic goes:

    if partial:           # ~60 lines up
       if not partial:
           ...

and we have kept it there for this long because the spec implies it.

(As a matter of fact I can't see how this entire `if partial` loop does
anything of consequence, given the previous loop didn't exclude the
partial case).

e33fe2bf24 KCC: pep8 conformance
I ran the files through the pep8 command-line tool.

Most changes are for line length, inline comment formatting, adjusting
numbers of blank lines, and the indentation of conditions on if
statements.

This is pretty useless work, but I thought I would have a go with the
pep8 tool, and it came up with a lot of complaints.

39da46e72c KCC: Help RW DCs to ignore RODCs when doing kcc
As far as writable DCs are concerned, RODCs don't even exist. So we make
tables that leave out the RO ones.

An RODC needs to know itself as well as writable DCs, so we add it in
that case.

2e9fefc738 KCC: use connect_table.values(), not .items() where that's best
The keys in dsa.connect_table objects are fairly arbitrary strings
(containing guids) and are of no use except when we're deleting
connections. Looping over the .items() clutters up the namespace and
potentially confuses or clobbers, given the hugeness of some of these
functions.

59af1b5175 KCC: fix is_bridgehead_failed() according to documentation
Throughout the KCC specification `detectFailedDCs` is documented along
the lines of "true to detect failed DCs", and it gets passed down to
this function. And what do we see here? It is used as a default value
when a stale link is not detected. That is entirely different. So who is
right -- the comments or the pseudo-code?

This commit follows the comments. It works!
