rsyslog changes for 2007-08-09

Yesterday I made a couple of changes:

– fixed a bug in outchannel code that caused templates to be incorrectly
– fixed a bug in ommysql that caused a wrong “;template” missing message
in some cases
– some text and code cleanup in cflineParseTemplate() to match the changed
design of selector handling
– added new doc files to autotools for make dist
– fixed a bug that would have manifested when module configuration commands
would have been freed. The current code base, however, never does this, so
this is not a real bug fix – it’s in preparation of future work
– fixed a potential memory leak in modules.c, again, this could not happen in
current code
– added interface API for unloading module (a dummy)
– added module unload functionality; rsyslogd now unloads modules on exit
(of course, with only statically linked modules, there is little current
value in this – but it is made towards an upcoming dynaload plugin interface)
