This was working before, but only if realloc a) succeeded and b) did not
move the buffer to a different location. ''**buf = **new_buf' then
writes the value of *new_buf's first field into that of *buf.

There is no special reason to use the secure version of getenv, thus let's
simply use getenv().

After commit 8250bc9f ("ss: Unify inet sockets output") raw sockets
are displayed as udp because dgram_show_line() is used for both and
thus IPPROTO_UDP is used for both so proto_name() returns "udp".
Fix this by checking dg_proto which is set according to the caller of
dgram_show_line().

Add a start of a man-page to the misc section as a reference and
guide on (e)BPF classifier and actions. Given that tc is only tersely
documented, this is provided in the hope that users will have an
easier getting started with tc and (e)BPF. And, that there's now more
incentive for others to also start documenting their classifier and
actions as well. ;)
