2022-02-01 security/krb5-117: EOL one year after the release of krb5 1.19

There have been lots of missing CONFLICTS_INSTALL entries, either
because conflicting ports were added without updating existing ports,
due to name changes of generated packages, due to mis-understanding
the format and semantics of the conflicts entries, or just due to
typoes in package names.

This patch is the result of a comparison of all files contained in
the official packages with each other. This comparison was based on
packages built with default options and may therefore have missed
further conflicts with optionally installed files.

Where possible, version numbers in conflicts entries have been
generalized, some times taking advantage of the fact that a port
cannot conflict with itself (due to logic in bsd.port.mk that
supresses the pattern match result in that case).

A few ports that set the conflicts variables depending on complex
conditions (e.g. port options), have been left unmodified, despite
probably containing outdated package names.

These changes should only affect the installation of locally built
ports, not the package building with poudriere. They should give an
early indication of the install conflict in cases where currently
the pkg command aborts an installation when it detects that an
existing file would be overwritten,

The conflict checks compare the patterns first against the package
names without version (as reported by "pkg query "%n"), then - if
there was no match - agsinst the full package names including the
version (as reported by "pkg query "%n-%v").

Many CONFLICTS definitions used patterns like "bash-[0-9]*" to filter
for the bash package in any version. But that pattern is functionally
identical with just "bash".

In addition, deprecate krb5-117 to retire one year after the release
of krb5-119: Feb 1, 2022.

krb5-119 becomes the default krb5 port.
