A wildcard search is divided into chunks by the asterisks. While most
chunks match the first suitable string, the last chunk matches the
last possible string (unless there is a trailing asterisk, in which
case this distinction is moot).
We always knew this in our hearts, but we tried to do it in a funny
complicated way that stepped through the string, comparing here and
there, leading to CVE-2019-3824 and missed matches (bug 14044).
With this patch, we just jump to the end of the string and compare it.
As well as being correct, this should also improve performance, as the
previous algorithm involved a quadratic loop of erroneous memmem()s.

As seen in CVE-2021-20277, ldb_handler_fold() has been making mistakes
when collapsing spaces down to a single space.
This patch fixes the way it handles internal spaces (CVE-2021-20277
was about leading spaces), and involves a rewrite of the parsing loop.
The bug has a detailed description of the problem.

(cherry picked from commit 24ddc1ca9cad95673bdd8023d99867707b37085f)
Previously, containment testing using the 'in' operator was handled by
performing an equality comparison between the chosen object and each of
the message's keys in turn. This behaviour was prone to errors due to
not considering differences in case between otherwise equal elements, as
the indexing operations do.
Containment testing should now be more consistent with the indexing
operations and with the get() method of ldb.Message.

These tests verify that the 'in' operator on ldb.Message is consistent
with indexing and the get() method. This means that the 'dn' element
should always be present, lookups should be case-insensitive, and use of
an invalid type should result in a TypeError.

Commit f469fc6 (2010-10-02) inadvertently caused the previous hop realm
to not be added to the transit path of issued tickets. This may, in
some cases, enable bypass of capath policy in Heimdal versions 1.5
through 7.2.
Note, this may break sites that rely on the bug. With the bug some
incomplete [capaths] worked, that should not have. These may now break
authentication in some cross-realm configurations.
