See script directory for method. The script to run in the top level
MaxScale directory is called maxscale-uncrustify.sh, which uses
another script, list-src, from the same directory (so you need to set
your PATH). The uncrustify version was 0.66.
The test methods that take printf style input now have the printf
attribute. This enables format checks making oversights less likely.
Also fixed any existing errors in the code. Only the one in
test_binlog_fnc.cpp would've had an actual effect.
If a MaxScale-generated configuration defines an empty value, it is
ignored with the assumption that the next modification will cause the
problem to correct itself.
Added some helper functions into the MaxScale class and default parameters
into the connection creation functions. Also made the ip() function const
correct.
