Bug#3944 -  Session closed if active data transfer fails due to "Address
already in use" error.
Bug#3983 - Change default SyslogLevel to be NOTICE rather than DEBUG.
Forgot to update copyright dates with last modification.
Add a .travis.yml file, to start using travis-ci for continuous
build/integration.  I'm sure we'll get fancier over time.
Install more dependencies, and build more modules, via travis-ci.
Build mod_geoip as well; we'll need its geoip library dependency as well.
Need the PAM libraries/headers for some modules.
Now install the check library, to enable the API/unit tests -- and run them.
Clean up build warnings spotted by travis-ci.
Make the dependency installations a little easier to read.  Build the
MySQL and Postgres modules.  Install gettext, so that we can use --enable-nls.
Fix another build warning spotted by travis-ci.
Enable memcache support.
Direct email notifications of build success/failures to the proftp-committers
list.
Start commenting the travis-ci config file.  Add some static code analysis in.
Keep cppcheck from scanning *every* file; use find to tell it which file to
scan.  Break the `make' and `make check-api' steps onto separate lines, for
legibility.
Use the direct email address to the -committers list.
More tweaks to the static code analysers.
Fix the cppcheck arguments.  Enable PCRE support.
Still wrestling with cppcheck.  Sigh.
Skip checking header files, and unit test files, when performing static code
analysis.
