Log fatal exceptions with stacktraces
Revert "Log fatal exceptions with stacktraces"

This reverts commit d2a9997692365eb1feafa4ef2d1f74fe1cc5bf84.
Replace URLDecoder with a faster alternative
Only create ByteBuf if needed
Remove unused class
Only try to adjust trafficClass if the user asks for.

This should lower the possibility to run into the problem when using windows.

Use relaxed parser to parse path and query parts out of an uri to prevent IllegalArgumentException when possible.

For absoluteURI() an URI is still constructed and so validated
Fix UriParser and add Http test
