The experimental multi-packet mode splits input bytes depending on a length
decoded from the first 2 bytes and does that until the end of input.
To use this mode, compile with "make D=-DLWIP_FUZZ_MULTI_PACKET"

This reverts commit 2390eb6826.
I've already marked other issues like this as 'invalid', so do this here, too.
Although I don't like the code, there's not much use in fixing this in one place only.
In contrast to netif_get_client_data, netif_alloc_client_data_id() is only
available if LWIP_NUM_NETIF_CLIENT_DATA > 0, not for DHCP etc.
This is correct in netif.c but wrong in netif.h
struct netifapi_msg is defined in lwip/priv/api_msg.h rather than
lwip/netifapi.h. Thus remove include of lwip/netifapi.h from memp.c.

See bug #50914( TCP_CHECKSUM_ON_COPY when adding data to
retransmission): when adding data to an already transmitted segment
that has an uneven length, the checksum was wrong.
To fix this, tcp_output_segment has to restore seg->chksum_swapped
before returning.
This triggers bug #50914 (TCP_CHECKSUM_ON_COPY when adding data to
retransmission) when data is added to an already transmitted segment
with an uneven length of tcp data.
enum tcpip_msg_type and struct tcpip_msg have members which are only
used when core locking and/or core locking input are disabled. Remove
these from the union to reduce the size. Remove from enum to prevent
usage when these are options are disabled
A quick sizeof test with MSVC 2013 showed a 4 byte size reduction for
struct tcpip_msg (16 bytes -> 12bytes) for the following configuration:
LWIP_TCPIP_CORE_LOCKING 1
LWIP_TCPIP_CORE_LOCKING_INPUT 1
LWIP_TCPIP_TIMEOUT 0
With the changes introduced in b1b6275110
it's no longer possible to get ERR_CLSD from netconn_recv_tcp_pbuf_flags
after we've received data because of the NETCONN_NOFIN flag, so remove
handling for this case. Further the NETCONN_EVT_RCVPLUS stays active in
netconn_recv_data_tcp when the NETCONN_NOFIN flag is used
FIN should only be reported once (as '0' for sockets, as 'ERR_CLSD' for
netconns). Before this change, ERR_CLSD was returned forever...
This is the 2nd try. First try (commit ebcae98ae6)
was buggy in that it could drop the FIN if it was read together with data
(reverted in commit ebcae98ae6).
This version fixes this by adding an apiflag and a netconn flag to keep
track of this.
Headers are never included here or else get_http_headers would not
have been called.
As a result, custom files need to set FS_FILE_FLAGS_HEADER_PERSISTENT
in file->flags if file->len is the correct length of the file.
