- added the $InputFilePersistStateInterval config directive to imfile
- changed imfile so that the state file is never deleted (makes imfile
  more robust in regard to fatal failures)

- bugfix: a couple of problems that imfile had on some platforms, namely
  Ubuntu (not their fault, but occured there)
- bugfix: imfile utilizes 32 bit to track offset. Most importantly,
  this problem can not experienced on Fedora 64 bit OS (which has
  64 bit long's!)

... plus some celanup and adding minor missing functionality
(the rule debug info again tell the property name, not just number).

some things inside the message can be used over a large number of
messages and need to to be allocated and re-written every time. I now
begin to implement this as a "prop_t" object, first use for the inputName.
Some input modules are already converted, some others to go. Will do
a little performance check on the new method before I go further.

Also, this commit has some cleanup and a few bug fixes that prevented
compiliation in debug mode (I overlooked this as I did not compile
for debug, what I normally do, and the automatted test also does not
do that)

WARNING: currently, message repeation processing is disabled, must
be reenabled (but prefer to do some other tests first)
