Remove the logic that creates my.cnf in basedir from mysql_install_db

This is a fix for upstream bug http://bugs.mysql.com/bug.php?id=68416.

Currently mysql_install_db installs a my.cnf file in basedir, which for
rpm and dpkg is /usr, with some common options. Since we don't want a
my.cnf created anywhere, this patch removes this code from the script
altogether.

In order to facilitate future merges, in particular if in the future the
bug gets fixed upstream (possibly adding an option not to install the
file but that keeps the code), the code is commented out and not deleted.
Move the UDF *.a and *.la files to the RPM devel package

The static libraries from the packaged UDFs were wrongly packaged to the
shared package, when they belong to the development files. Additionally,
this was introducing spurious conflicts with the 5.6 shared package
(which suffers from the same bug).
Move the UDF *.a and *.la files to the RPM devel package

Merge the fix from 5.5. Also, readd the libmysqlclient.so file to the
devel package (taken off from the client package), which was removed
incorrectly at some point.
Do not pack the libmysqlclient.so.16 library link in the shared package

Do not pack the unversioned symlink in the shared package, since it gets
created by ldconfig(8) after install anyways. This helps not having
conflicts with upper versions of the library.
Remove the mysql.info file

Remove the mysql.info file from the distribution. Besides it being
pointless (it was just a link to the online documentation), it created
conflicts between the 5.5 and 5.6 versions of the library.

Merge of the fix from 5.5.
Change libmysqlclient18 to libmysqlclient18.1
Do not package the libmysqlclient.so.18 links in the library packages

Do not package this links since they are created by ldconfig(8) anyway
after installation. This will prevent conflicts between higher versions
of the libraries.

For debian, this also means adding a manual link since on install links
that are not pointing nowhere won't be created, and the fully versioned
libmysqlclient_r library is a symbolic link to the unversioned library,
instead of to the fully versioned.
Do not package the libmysqlclient.so.18 links in the library packages

Merge the change from 5.5.

Bump versions to 5.6.13-61.0
Do not conflict with Percona-Server-shared-55

Do not conflict with the 5.5 version of the package, since now that
version provides libmysqlclient.so.18.0.0 and this one
libmysqlclient.so.18.1.0.

Removal of libmysqlclient-dev package

libmysqlclient-dev is now provided by the 5.6 branch, and this package
has become libmysqlclient18-dev. The former libmysqlclient18-dev package,
which used to be an empty package depending on libmysqlclient-dev, was
now removed.
