In keeping with pbuf->ref always having the count of the number of pointers
...
to the particular buffer (and the last rewrite of pbuf_free), changed most
pbuf_ref_chain() calls back to pbuf_ref(). I think this was causing some pbuf
leaks.

after being freed. Also, it was not being freed if it had been the first
buffer in chain. It still needs to be freed then.

Fixed up and made work a PBUF_REF type. Most of the code uses this now
...
instead of PBUF_ROM. This addition allows support of copy-on-demand where the
lower layers can call pbuf_unref() which tests for any PBUF_REF buffers and
replaces them with PBUF_POOL buffers. This is now used
everywhere. pbuf_unref() is called in ARP queueing and in the coldfire
driver, which puts frames on a DMA queue and frees them later.
Along with this change pbuf_free() now goes through the entire chain of
buffers and tests all the ref counters, not just the first one. Generally now
pbuf_ref_chain() should be called and not pbuf_ref(). This change was made
because it is possible for the head of the pbuf chain to have a different
count than the payload pbuf which might have been passed by the application.
