libedit changed its interface a while back. mariadb currently does not
recognize this interface and instead uses a static old readline version.
It does not link in the system readline due to licence incompatibility.

This commit adds a patch that enables mariadb to detect and use the
system libedit. The patch was sent upstream already ([1]).

Bump to 10.2.x release series which has support for OpenSSL 1.1.x.

- libmariadbclient was replaced by libmaria
- libmaria uses LGPL, hence license info updated
- upstream disabled xtradb engine, innodb is now default (cannot be
  built as plugin anymore)
- complex charsets are now all included (size increase), as otherwise
  compile fails
- patches adapted/refreshed
