* pcap: reuse Frame memory
* slog: reduce heap allocations of addresses; also prevent heap alloc of dhcp options in pcap
* dns: heapless improvement; add StackAsync buffer for more heapless operation; start thinking of errors
* errors: begin standardise errors in lneto
* errors: finish standardization of errors
* fix merge issues
* add more lneto errors to rest of package
* format errors.go
* improvements to dhcpv4 server
* begin adding examples/httpserver
* add better VLAN tagging methods
* pcap: add error printing; fix bug in CRC
* ipv4: ToS and Flags construction and flag manipulation improvements
* add dhcp interception to httptap and improve httpserver example
* Simplified checksum calculation and verification
* Fixed tests
* UDP: using NewBoundedFrame to create a Frame instance limited to the actual frame size.
* Minor: renamed some functions
* Commented and made more readable consecutive SetCRC calls.
* Fixed icmp checksum calculation after rebase
* Replaced NewBoundedFrame with explicit validation
* Checksum 0x0000 is returned as 0xFFFF (mandatory for UDP, common for TCP)
* Both checksum zero values (0x0000 and 0xFFFF) are accepted when receiving
* Rename parameter in VerifySum16 to expectedSum16
