Axel Dörfler 750b92faf3 Almost rewrote LinkMsgSender; it's now much cleaner and works better:
- StartMessage() can now get a size to make sure there is enough free space
- if StartMessage() is called with the current message behind a certain
  watermark, the buffer is flushed in order to prevent moving around messages
  in the buffer. The actual value should be tested in real life, though.
- enlarged maximum buffer size to 64k
- fixed bug: could use memcpy() to move overlapping memory around
- added a flag to Flush() that marks messages as needing a reply - the other
  way would be to mark the message "code" to contain this information

Some cleanup in LinkMsgReader.
BPortLink now has most methods as inlines.
The buffer sizes are now declared in a shared header, so that receiver and
sender are always equipped equally.
