Sprint: 10.2.4-1

 Description   

Setting a fake version string does not only change what version number clients see, but also what server version is printed to the error log.

This should either show the real version, or both the "real" and "faked" version.

Otherwise things can become really confusing when trying to analyse error logs ...

I have 

[mysqld]
 
version=1.2.3

in my.cnf and the startup messages in the error log look like this:

It is actually correct at the beginning of the startup messages:

161008 13:09:06 mysqld_safe Starting mysqld daemon with databases from /usr/local/mariadb-git-hartmut-MDEV-10541/var
 
2016-10-08 13:09:06 140571076974784 [Note] /usr/local/mariadb-git-hartmut-MDEV-10541/bin/mysqld (mysqld 10.2.3-MariaDB as 1.2.3) starting as process 7174 ...

but not at the end when the server actually becomes ready:

2016-10-08 13:09:06 140571076974784 [Note] /usr/local/mariadb-git-hartmut-MDEV-10541/bin/mysqld: ready for connections.

using 10.2.4 version, using "version=10.2.4-diego" in my.ini ,
driver still receive the "fake" version "5.5.5-" prefix. (driver in my example receive "5.5.5-10.2.4-diego")
