While I was creating Debian packages for the "MariaDB Client Library for C" I came across several minor issues that I corrected.  I thought I'd post the patches here in case you might be interested in integrating them; I'd have no problem with contributing them under the MCA if that's necessary (i.e. if they're even big enough to require such a thing).  Each one has a fairly complete description of its purpose at the start.

I've also noticed that mariadb_config --libs prints out something like ... -l-lz if WITH_EXTERNAL_ZLIB=ON.  However, for the Debian packages I instead patched mariadb_config to remove the indirect dependencies altogether, as we generally do, so I didn't write a fix for the -l-lz issue.  Also, it seems that if I try to build with WITH_SQLITE=ON then I get a build error, so I haven't enabled that in the Debian packages.
