Subject: [PATCH 1/8] mariadb: use system libedit for mysql

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]).

+    cmake: support new libedit interface
+    
+    libedit changed it's interface a while ago. MariaDB's cmake file doesn't
+    recognize the new interface, the compile test fails:
+    
+    /mariadb-10.2.19/CMakeFiles/CMakeTmp/src.cxx: In function 'int main(int, char**)':
+    /mariadb-10.2.19/CMakeFiles/CMakeTmp/src.cxx:6:47: error: invalid conversion from 'char*' to 'int' [-fpermissive]
+      int res= (*rl_completion_entry_function)(0,0);
+               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~
+    
+    Fix this by adding a detection for the new interface as well.
+    
+    In client/mysql.cc the ifdefs for the new readline interface are
+    extended to also check for the new libedit interface. They work the same
+    way.
+    
+    Run-tested on a MIPS machine.

Subject: [PATCH 2/8] mariadb: refresh plugins

This commit deals with changes related to plugins and how they're built
or disabled.

Currently a lot of plugins are packaged which are merely for tests or
plain examples. Other distros do not bundle these, hence this commit
does away with them.

A few new plugins are added related to PAM and Kerberos (auth_gssapi,
auth_gssapi_client and auth_pam).

The BuildPlugin template is refactored to also allow building of library
plugins (needed for auth_gssapi_client). The template is also cleaned up
- some extraneous dollar signs are removed and the install function is
now defined outside the template.

Unwanted plugins/engines are now turned off efficiently (without using
cmake variables) by blanking CMakeLists.txt files in the associated
folders. The idea was lifted from Gentoo.

ha_sequence is now built into the server. This is an upstream
preference. The plugin is about 30 kbytes in size, so there is no harm
adding it into the server, which weighs in at about 15 Mbytes anyway.

Last but not least the auth_socket plugin is now also built into the
server.  This allows the local root user to login to the database
without a password being set. This makes maintenance easier without
being detrimental to security. The idea was lifted from Debian.

Subject: [PATCH 4/8] mariadb: improve packaging and configuration

At present there are some flaws related to configuration, also related
to the packaging of mariadb. For starters there are complaints that the
configuration is too static.

To address this a new configuration layout is introduced. The primary
configuration file (my.cnf) is changed so that it now only includes
further configuration files in the directory /etc/mysql/conf.d. More
default configuration files are added for the server and the client.
This is the new default configuration.

With these changes it's possible for the user to select if they want to
change the default configuration (in conf.d/*.cnf) or if they want to
drop their own files into conf.d instead. If the user .cnf files are
read after the default .cnf files (files are included in alphabetical
order), they will overwrite the settings from the default configuration.

The other flaw is that the my.cnf file is included in mariadb-server.
But that doesn't really fit the requirements, as the client also uses
the configuration file(s). To accomodate this a new package
mariadb-common is added. It installs the shared my.cnf file.

The remaining changes add base packages, both for the server and the
client. These are meant as foundation for the packages containing the
respective binaries. In summary they will install the configuration,
small miscellaneous files (SQL scripts etc.) and the user "mariadb".

That means that everything is ready for the binaries, like mysql and
mysqld. If there is not enough space left on flash memory, the user can
just drop the binaries on a pendrive, link them to /usr/bin and get
started.

The ideas and configuration files were copied from Debian. Some
amendments were made.

+# to four bytes per character) this was changed. Now the baked in-defaults are
+# the upstream defaults (Latin1), but in the default configuration (like in the
+# file you are currently reading) utf8mb4 is set, which is real UTF-8.
+#
+# Of course you are free to change this, either here or in a configuration file

Subject: [PATCH 5/8] mariadb: add extra charsets to server base

There is little sense in keeping these charsets in an extra package. The
included sets are of the single byte character set variety. They only
amount to a few kbytes.

Subject: [PATCH 8/8] mariadb: update init script to use uci

Does away with /etc/default/mysqld, introduces uci configuration
instead. The init script receives some further brushing up, like a
function (copied from Debian) to get mysqld configuration parameters
easily and quickly.
