Bugfix: if the cc2420_cca() function wasn't able to turn on the radio properly, it should turn it off again if it was off before.

Renamed nullrdc to nullrdc-noframer and nullrdc-framer to nullrdc.
...
nullrdc (previously nullrdc-framer) is now a RDC implementation that
does not do any radio duty cycling but supports link layer addresses
and frame format via framer (for example 802.15.4). nullrdc can now be
used in the same way as contikimac, xmac, etc.
nullrdc-noframer (previously nullrdc) is a null RDC implementation
that does not do any radio duty cycling, does not add any header of its
own to the packets, and does not support link layer addresses.

Minor clarifications in the code and comments. Integrated atches from Frederic Sureau: 1. copy_buf is now an ordinary char pointer. 2. Read directly from a file that is not modified. This reduces the code size when COFFEE_MICRO_LOGS is set to 0. 3. Update the file end value each time it is changed in case a log merge operation occurs later. 4. Avoid possible alignment problem in reading from the dummy_space area when calling cfs_readdir.

When IPv6 ND kicks in, the packet that caused the ND can either be dropped or saved in a buffer to be send when the NS reply returns. This commit reimplements the buffer management to avoid having one buffer per neighbor, but instead use a buffer pool from which buffers can be allocated for different neighbors.

A simple but substantial change: uIP used the htons()/HTONS() macro
...
functions for converting between host and network byte order. These
names are the de facto standard names for this functionality because
of the original BSD TCP/IP implementation. But they cause problems for
uIP/Contiki: some platforms define these names themselves (Mac OS,
most notably), causing compilation problems for Contiki on those
platforms.
This commit changes all htons to uip_htons instead. Same goes for
htonl, ntohs, and ntohl. All-caps versions as well.
