Update to V2.0.7 of the TCP/IP stack:
   + Multiple security improvements and fixes in packet parsing routines, DNS
     caching, and TCP sequence number and ID generation.
   + Disable NBNS and LLMNR by default.
   + Add TCP hang protection by default.

We thank Ori Karliner of Zimperium zLabs Team for reporting these issues.

/**
* This method generates a checksum for a given IPv4 header, per RFC791 (page 14).
* The checksum algorithm is decribed as:
* "[T]he 16 bit one's complement of the one's complement sum of all 16 bit words in the
* header. For purposes of computing the checksum, the value of the checksum field is zero."
*
* In a nutshell, that means that each 16-bit 'word' must be summed, after which
* the number of 'carries' (overflows) is added to the result. If that addition
* produces an overflow, that 'carry' must also be added to the final result. The final checksum
* should be the bitwise 'not' (ones-complement) of the result if the packet is
* meant to be transmitted, but this method simply returns the raw value, probably
* because when a packet is received, the checksum is verified by checking that
* ((received & calculated) == 0) without applying a bitwise 'not' to the 'calculated' checksum.
*
* This logic is optimized for microcontrollers which have limited resources, so the logic looks odd.
* It iterates over the full range of 16-bit words, but it does so by processing several 32-bit
* words at once whenever possible. Its first step is to align the memory pointer to a 32-bit boundary,
* after which it runs a fast loop to process multiple 32-bit words at once and adding their 'carries'.
* Finally, it finishes up by processing any remaining 16-bit words, and adding up all of the 'carries'.
* With 32-bit arithmetic, the number of 16-bit 'carries' produced by sequential additions can be found
* by looking at the 16 most-significant bits of the 32-bit integer, since a 32-bit int will continue
* counting up instead of overflowing after 16 bits. That is why the actual checksum calculations look like:
* union.u32 = ( uint32_t ) union.u16[ 0 ] + union.u16[ 1 ];
*
* Arguments:
* ulSum: This argument provides a value to initialize the progressive summation
* of the header's values to. It is often 0, but protocols like TCP or UDP
* can have pseudo-header fields which need to be included in the checksum.
* pucNextData: This argument contains the address of the first byte which this
* method should process. The method's memory iterator is initialized to this value.
* uxDataLengthBytes: This argument contains the number of bytes that this method
* should process.

Changes since V2.0.0 release
Changes between 160919 and 180821 releases:
+ Multiple security improvements and fixes in packet parsing routines, DNS
caching, and TCP sequence number and ID generation.
+ Disable NBNS and LLMNR by default.
+ Add TCP hang protection by default.
We thank Ori Karliner of Zimperium zLabs Team for reporting these issues.
+ Update FreeRTOS_gethostbyname() to allow an IP address to be passed in -
in which case it is just returned as a uint32_t.
