While a BinaryDn.prefix is generated in upper-case, and
dsdb.DS_GUID_DELETED_OBJECTS_CONTAINER is upper-case, we can avoid
having to think about that by comparing the actual bytes.

dsdb_Dn() was a catchall for DN+Binary, DN+String, and plain DNs which
needed to be sorted in a particular way. This meant it treated none of
them exactly right.
For example, a binary dsdb_Dn would be compared on the string
representation of the binary portion, so 'B:2:ff:CN=foo' would not
equal 'B:2:FF:CN=foo', when it should.
It meant a field that expected a binary dsdb_DN would also accept a
plain DN or a string DN, which is never actually allowed.
Also the parsing was a bit dodgy, so a string like 'B:6:ff:CN=foo'
would be accepted, when the length of the binary portion ("ff") is
obviously different from that given ("6").
Here we solve many of the problems by making stricter subclasses but
leaving a compatibility shim in place so that existing code continues
to work.
There is one INCOMPATIBLE change. Previously the `.binary` attribute
of a dsdb_Dn was the hex-string, while now it is the actual binary
data. In the case of StringDn, this means the utf-8 bytes.
This affects dbcheck, which is fixed here (the .prefix assignment now
correctly sets .binary).

The fact that get_wellknown_dn() returned a cached DN that could
not be modified safely was unexpected, particularly given that
other similar routines did not do that.
The use case given at the time this was written by
Matthieu Patou in 6122acad0f
was dbcheck, so move the cache there, and name it clearly.
dbcheck is the only case that uses this rotuine in an inner
loop.

The dbcheck module is used in places other than samba-tool (backup,
provision) where the old 'use --fix' message made no sense. Also,
now that we're not necessarily claiming to fix all errors, we say
how many we think we can.

Prefixes like ERROR, WARNING, and INFO are given interpretive colours.
This won't change anything until samba-tool decides to ask for colour,

This function provides a simpler method of getting the bounds of the
range of RIDs we want to check. We also now check that the low bound is

This made Python 2's print behave like Python 3's print().
In some cases, where we had:
from __future__ import print_function
"""Intended module documentation..."""
this will have the side effect of making the intended module documentation
work as the actual module documentation (i.e. becoming __doc__), because
it is once again the first statement in the module.

These reports (about recently deleted objects)
create concern about a perfectly normal part of DB operation.
We must not operate on objects that are expired or we might reanimate them,
but we must fix "Deleted Objects" if it is wrong (mostly it is set as being
deleted in 9999, but in alpha19 we got this wrong).

The construct `'name' in map(str.lower, attrs)` is doubly inefficient,
because not only is it running the lower() function too often, it is
searching linearly in a temporary iterator for membership.
So we make a set, and use that.
