2022-04-14 lang/gcc9-devel: Not serving its purpose any longer due to lack of
maintenance

lang/gcc9-devel: Deprecate port

The purpose of lang/gcc9-devel and other lang/gcc*-devel ports
was to track GCC's weekly snapshots, serve as a canary for the
next update of the corresponding lang/gcc* port that tracks minor
releases, and provide bleeding edge for users who desire so.

Since I relinquished maintainership more than five months ago
(commit 11a44652a8f922adcc84d5056807e96a389fc471) there has not
been an update and the port is stuck at the 20211007 snapshot.

It thus has not been serving its purpose any longer for a while
and GCC 9 is reaching end of life, so deprecate the port for
removal more than half a year after the latest version update.

Fix CONFLICTS entries of multiple ports

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

lang/gcc9-devel: Relinquish maintainership

After working on (and largely maintaining) our GCC ports for more than
19 years, time has come to hand over the baton. Sadly despite multiple
requests nobody stepped up, so return this port to the pool.

Still happy to provide guidance and a helping hand, for example working
with upstream or on operating the (crucial) nightly testers I have been
running.

Bump all directly dependent ports. Do not bump those indirectly
dependent via the lang/gcc* family since their run-time dependencies
and code generated should not be affected.
