d65681a7d7 DHCP request send on reboot does not contain hostname option 
When the network is changed, dhcp is rebooted.
It will send a dhcp request again to verify it's lease.

DHCP requests are send out in selecting state, rebinding, renewing
and rebooting. But in the rebooting state the hostname option is
not included. This means that after reboot, the hostname will be
unknown to the DNS.

19a929f5fb dhcp: fix parse error with chained pbfus 
If a chained pbuf starts with DHCP_OPTION_PAD, an overflow check
triggers and the packet is ignored.

Fix this by changing the way the offset is increased for PAD.
Also ignore a packet that is missing the END option.

7d1c6ba549 dhcp: Fix BOOTP_FILE bug 
The comment in dhcp_handle_ack for 'offered_si_addr' states:
'boot file name copied in dhcp_parse_reply if not overloaded'
However this code was never reached if the packed was not 'overloaded'

ff03ae6f55 dhcp: restart dhcp after releasing. 
There were uses of dhcp_release() followed immediately by dhcp_discover() but
dhcp_release() now stops dhcp so discovery would fail, so call dhcp_start()
after release which restarts discovery.

Old dhcp_release() and dhcp_stop() function internally call dhcp_release_and_stop() now.

Make functions easier to override in cc.h. The following is sufficient now (no more LWIP_PLATFORM_BYTESWAP):
#define lwip_htons(x) <your_htons>
