if a pbuf received with the same seqno in ooseq ,
we then check the size and replace the existing one
with the larger one,but if the existing one is the
last segment in ooseq ,it might has been trimed before.
the replacing action will overrun our receive windows
see patch #10106 and bug #56397
Allow one to provide a custom implementation of free/malloc/calloc
instead of the lwip internal allocator. The code to use the libc's
implementation already existed, so generalize the existing code and make
the libc variant a specialized case of this new capability, retaining
full backwards compatibility.

lwIP might support different hardware address lengths (when using
Ethernet and 6LoWPAN for instance). Match provided lladdr length
from Router Advertisement to the current network interface instead
of comparing against longest that can be stored.
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.

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
