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
There was a lot of files generated by the sources that were not installed
in any package. This fixes most of those issues, but not all. Files still
outside any package are in the not-installed, which is used by dh_install.
Also make sure all configuration files are installed to the correct
location that matches layout used by Debian official packages.
There is no need for a separate mariadb-test metapackage and a versioned
mariadb-test-* package. Simply make it versionless and make it depend on
the client and server packages that stem from same source version.
