124106: correct handling of paragraph attributes, esp. whose which are providing the default value explicitly

i118640 force early destruction of last FragmentHandler to not let it use an already destroyed RelationsMap instance

delaying the initial event prevents complaints from OSX>=10.7's "windows restore"
feature to recur infinitely. Apparently OSX cleans things up for us just before
we get the applicationDidFinishLaunching() callback. This should solve one of the
most popular support questions for AOO on Mac for good.

#i118923# OS/2 port, report correct error string in case of dlopen() failure, rewrote code to use more dl* functions.

the fix works also for EditEngine by ignoring Writer's halfspace magic.
TODO: replace that halfspace magic with a generic solution.

124188: <SwDoc::InsertDrawObj(..)> - assure correct insertion of text attribute for as-character anchored drawing objects

Thx to Andre for his deep analysis.
