Sample:

Receive mailbox contains 4 packets each 1000 bytes.
Application makes recv() for 1 byte.
It will be receive window update sent, as if
application 1000 received.

The problem is, that receive buffer is separated to two parts:
receive mailbox and sock->lastdata.
Lwip considers that data in sock->lastdata processed immediately.
But application can take only part of the data from sock->lastdata.
And windows update should be sent only to the part that application realy received.
