Updated llstring to current linden
Further linden_common cleanup
Header cleanup
Raised banlines to 5000 as per linden server change
Included missing llmediaentry.cpp file
Minor whitespace changes here and there
This involves making libllcommon shared, a change
that was not finished for windows/Mac.
More changes are needed to indra/newview/viewer_manifest.py
for those two operating systems, as well as to
indra/copy_win_scripts.
I did not test this on linux 32bit, nor non-standalone
on that OS, either.
I did not check voice (which will very likely not work
anyway on 64bit). And currently the webkit plugin doesn't
work for me, but I'll fix that in a different commit.
