out_flags was being set but never used.

Use just random() to allocate initial sequence numbers; the previous
algorithm ended up with a high probability of zeroing the high word.

Clarified packet ownership transfer between a few functions.
...
Added a large number of missing calls to free_pkb(). In the case of UDP,
no received packets were ever freed, which lead to memory exhaustion
remarkably quickly once pxelinux started up.
In general, any function with _rx() in its name which accepts a pk_buff
*must* either call free_pkb() or pass the pkb to another _rx() function
(e.g. the next layer up the stack). Since the UDP (and TCP) layers don't
pass packet buffers up to the higher-layer protocols (the
"applications"), they must free the packet buffer after calling the
application's newdata() method.

architecture-independent.)
