NOTE TO MERGERS: This commit should be upstream to MariaDB 10.4 only!
Merging to MariaDB 10.5 and above leads to major problems.
No functional changes.
Apply this in 10.3 so eventually it is merged to 10.4 and 10.5, which
in turn will have separate wrap-and-sort runs but only for new lines,
and not affecting badly next merges from 10.3 to 10.4 to 10.5.
Also remove a duplicate line that was found thanks to wrap-and-sort.
post-merge fixes:
* .gitignore
* don't put the keyword COMPONENT into ${COMP} anymore
* don't alias mytop, but do alias mysql_client_test
* don't symlink manpages, use troff aliasing technique instead
(symlinked manpages break rpm and out-of-source bintar builds)
* move debian to use troff aliased manpages, fix typos in debian files,
put aliases in the correct packages, add more aliases to match
rpm/bintar packaging
