90b2a6b4c4 dhcp: Set hostname for DISCOVER packets
If the hostname is not set in the DISCOVER packet, then some servers might
issue an OFFER with hostname configured and consequently reject the REQUEST
with any other hostname.

5231c8da23 dhcp: Enable custom config for timeouts, thresholds, backoff time
Enables to configure:
* DHCP_COARSE_TIMER_SECS
* if DHCP_DEFINE_CUSTOM_TIMEOUTS defined these addtional options are
available:
  - DHCP_CALC_TIMEOUT_FROM_OFFERED_T0_LEASE to adjust the t0 lease timeout from the offered value
  - DHCP_CALC_TIMEOUT_FROM_OFFERED_T1_RENEW same for t1 renew
  - DHCP_CALC_TIMEOUT_FROM_OFFERED_T2_REBIND same for t2 rebind
  - DHCP_NEXT_TIMEOUT_THRESHOLD to adjust the period of the next timeout
  - DHCP_REQUEST_BACKOFF_SEQUENCE to adjust back-off times based on DHCP
request attempts
Also updates timeout type from u16 to u32 - eps useful when DHCP_COARSE_TIMER_SECS is a smaller number

e8b0324f81 test/fuzz: Don't crash with assertion failure when a packet is too big
A fuzzer may generate big packets, and it will interpret assertion
failures as bugs. Instead of asserting that the packet size is
reasonable, simply skip the packet when it's not the case.

9f7d9170c1 netif: fix the netif's index error
When using multiple netifs on one hardware interface (e.g. when mapping multiple IP addresses to one hardware interface), if the netif's low-level receive routine cannot decide for the correct netif, here the `netif` parameter may be a default netif, in this case, `p-> if_idx` will get a wrong netif index value. It should be placed after `netif = LWIP_ARP_FILTER_NETIF_FN(p, netif, lwip_htons(type));`.  Filter function can returns the correct netif before assigning `p-> if_idx`.
