DBD::mysql new development release, test our unicode improvements!

(if you rather read a website than plain text, this is also on my
site: https://huntingbears.nl/2017/03/02/dbdmysql-even-more-utf8-issues-fix=
ed-super-ci/)

In my previous mail
(https://huntingbears.nl/2016/12/14/dbdmysql-all-your-utf-8-bugs-are-belong=
-to-us/)
I explained how many utf-8 related issues are now fixed in the latest
DBD::mysql development release, and I asked for feedback and testing
from our users.

Even better utf-8 handling
----------------------------------
I'm happy to inform you that, thanks to your feedback, we've now
released yet another development version, with even more UTF8 issues
fixed. Tanabe Yoshinori reported that column names and database
warnings were not properly encoded and prolific contributor Pali Roh=C3=A1r
fixed that issue, and much more.

Serialization issue under taint mode
----------------------------------------------
One other issue which was reported by amavisd users has to do with how
perl stores values internally under taint mode, which is the default
way amavisd is run. This is now fixed, see for more information
https://github.com/perl5-dbi/DBD-mysql/issues/78

Extreme CI testing setup
--------------------------------
And Pali also modified our Travis setup so we now do continuous
integration testing not only on many different perl versions, but also
using many different MySQL and MariaDB versions. This uncovered many
smaller and larger issues and we can compile again all the way back
with MySQL against version 4 if you would want that (and we had
multiple people wanting that and filing bug reports for this in the
past). See our .travis.yml file here:
https://github.com/perl5-dbi/DBD-mysql/blob/master/.travis.yml

This also lead to Pali discovering a use-after-free security issue in
libmysqlclient which was fixed in MySQL 5.6 and up but still present
in 5.5 and also in MariaDB. It got assigned CVE identifier
CVE-2017-3302 -
https://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2017-3302  - see
for more info this thread on oss-security:

Your feedback is welcome!
----------------------------------
Find the full change log below; when all is well on Wednesday 8th of
March we'll release the stable version 4.042, including all these
changes, as well as the changes from the previous post.
