Nowadays many HTTP server set cookies which may easily result in HTTP header fields longer than our 'httpheaderline' buffer. It doesn't hurt if we can't parse them but we need to be able to skip them and continue to parse the following header fields.
WWW_CONF_MAX_URLLEN is used as length for the 'editurl' textentry widget. The CTK code for handling that widget uses a single byte so the length can't be > 255. Thus WWW_CONF_MAX_URLLEN can't be > 255 as well.
* Fix CCA detection in Cooja in the case when the receiver swicthes on the right channel during an ongoing transmission. Always add a connection on transmission, even when the channel is not correct. Initially the connection is in a dormant state; this mimics what Cooja is doing when the receiver radio is turned off;
when the receiver is turned on and switched to the right channel, `updateSignalStrengths()` is called, and the connection starts to recieve PHY-level traffic.
* Add "channel" property for DGRM edges.
* Avoid cross-channel interference on DGRM and MRM radio mediums
Only the interrupt flags that have been handled must be cleared.
Otherwise, if a new interrupt occurs after the interrupt statuses are
read and before they are cleared, then it is discarded without having
been handled. This issue was particularly likely with two interrupt
trigger conditions occurring on different pins of the same port in a
short period of time.

Power-up interrupts do not always update the regular interrupt status.
Because of that, in order not to miss power-up interrupts, the ISR must
handle both the regular and the power-up interrupt statuses.

Introduce new useful GPIO macros to:
- get the raw interrupt status of a port,
- get the masked interrupt status of a port,
- get the power-up interrupt status of a port.
These macros are cleaner and less error-prone than raw register access
code copied all over the place.

Behave just like the CS8900A driver: Both the CS8900A and the LAN91C96 dynamically share a buffer for received packets and packets to be send. If the chip is exposed to a network with a lot of broadcasts the shared buffer might fill quicker with received packets than the 6502 reads them (via polling). So we might need to drop some received packets in order to be able to send anything at all.
ipv4/uip.c will not even be include in the list of sources in the first place if we are building with NETSTACK_CONF_WITH_IPV6 (CONTIKI_WITH_IPV6). Thus, there is no longer a need to wrap the entire source code in an #if guard.
