Fixed string truncation warnings by reducing max parameter lengths by one
where applicable. The binlogrouter filename lengths are slightly different
so using memcpy to work around the warnings is an adequate "solution"
until the root of the problem is solved.
Removed unnecessary CMake policy settings from qc_sqlite. Adding a
self-dependency on the source file of an external project has no effect
and only caused warnings to be logged.
The line length limitation is now increased to 16384 bytes. It is now
clearly documented in the limitations document.
The configuration parser now uses memory from the heap instead of the
stack. This should remove any problems caused by the larger line length.
