Even if fclose fails the stream is inaccessible and the second fclose
might cause memory violation.
Linux manpage says:
Upon successful completion 0 is returned. Otherwise, EOF is returned
and errno is set to indicate the error. In either case any further
access (including another call to fclose()) to the stream results in
undefined behavior.
Fixes: CID#57958

This is a mostly cosmetic change. Instead of separate buffer handling
functions, reduce some code duplication by using a side_idx just like the
plane_idx, with arrays.

Force passing a restart counter, by adding such arg to gtphub_start() (test
suite is not affected by this).
In gtphub_main.c, add -r,--restart-file <path> and next_restart_count() to
maintain the counter file. While at it, tweak the cmdline help to unify the
formatting (mostly commas and a missing line break).
Send gtphub's own restart counter. So far, the sender's restart counter was
copied through, which would break as soon as more than one GSN would talk to
the same peer with differing restart counters.
Also fix the in-mem restart counter data type (one octet, not two).

Start adding VTY commands to show rate counters / statistics / cache dumps.

First steps towards a new GTP hub. The aim is to mux GTP connections, so that
multiple SGSN <--> GGSN links can pass through a single point. Background:
allow having more than one SGSN, possibly in various remote locations.
The recent addition of OAP to GSUP is related to the same background idea.
(This is a collapsed patch of various changes that do not make sense to review
in chronological order anymore, since a lot of it has thorougly transmorphed
after it was first committed.)
