Vadim Yanitskiy 0c15e0baac DbgMuxConnHandler: accumulate DataBlockCount 
Looking at samples/k800_tems.pcapng.gz I noticed that the client
side (TEMS Investigation) is accumulating the FlowControl credits.
Below is an extract from it, showing the client sending three
data blocks in one go:

  DebugMux Tx frame (Ns=007, Nr=014, fcs=0xbda2) ConnData 00940900022c0104690103
  Container:
    ConnRef = 0x9400
    Data = hexundump("""

    """)

    Data = hexundump("""

Vadim Yanitskiy 3f1aa65e72 DbgMux{Frame,ConnHandler}: DataBlockLimit != DataBlockCount 
DataBlockLimit seems to be the maximum ConnData block size, which
has nothing to do with the flow control.  At least because we
always get a non-zero value even for Rx-only DPs.

Vadim Yanitskiy afed084c77 DbgMuxConnHandler: proper handling of the FlowControl message 
A FlowControl message basically indicates how many data blocks the
remote side is able to receive from us.  Whenever the block limit is
reached, we should queue outgoing data blocks until the remote side
has given us a new quote by sending another FlowControl message.
