After commit a233caa0aa ("json: make pretty printing optional") I get
following build failure:
LINK rtmon
../lib/libutil.a(json_print.o): In function `new_json_obj':
json_print.c:(.text+0x35): undefined reference to `show_pretty'
collect2: error: ld returned 1 exit status
make[1]: *** [rtmon] Error 1
make: *** [all] Error 2
It is caused by missing show_pretty variable in rtmon.
On the other hand tc/tc.c there are two distinct variables and single
matches() call that handles -pretty option thus setting show_pretty
will never happen. Note that since commit 44dcfe8201 ("Change
formatting of u32 back to default") show_pretty is used in tc/f_u32.c
so this is first place where -pretty introduced.
Furthermore other utilities like misc/ifstat.c and misc/nstat.c define
pretty variable, however only for their own purposes. They both support
JSON output and thus depend show_pretty in new_json_obj().
Assuming above use common variable to represent -pretty option, define
it in utils.c and declare in utils.h that is commonly used. Replace
show_pretty with pretty.

Prevent passing NULL FILE pointer to fgets() later.
Fix both tools in a single patch since the code changes are basically
identical.

SCTP module was not load by default. But this should be OK since we will not
load table if fdopen() failed, also opening the proc file won't load SCTP
kernel module.

This patch was generated by the following semantic patch (a trimmed down
version of what is shipped with Linux sources):
@@
type T;
T[] E;
@@
(
- (sizeof(E)/sizeof(*E))
+ ARRAY_SIZE(E)
|
- (sizeof(E)/sizeof(E[...]))
+ ARRAY_SIZE(E)
|
- (sizeof(E)/sizeof(T))
+ ARRAY_SIZE(E)
)
The only manual adjustment was to include utils.h in misc/nstat.c to make
the macro known there.

Since the relevant code (and it's bugs) is identical in both files, fix
them in one go. This patch fixes multiple issues:
* Using 'int' for the 'tdiff' variable does not suffice on 64bit
systems, the assigned initial time difference makes it wrap and
contain a negative value afterwards. Instead use the more appropriate
'time_t' type.
* As far as I understood the code, poll() is supposed to time out just
at the right time to trigger update_db() in the configured interval.
Therefore it's timeout must be set to the desired interval *minus* the
time that has already passed since then.
* With the last change to the algorithm in place, it does not make sense
to call update_db() before returning data to the connected client.
Actually, it never does otherwise we could skip the periodic updates
in the first place.

Although not fundamentally necessary to check return codes in these
spots, preventing the warnings will put new ones into focus.

Something like that maybe ?

SNMP counters can be provided as 64bit numbers.
nstat needs to cope with this even if running in 32bit mode.

New command line flag to output statistics in JSON format.
In our envrionment, we have scripts that parse output of commands.
It is better to use a format supported by existing parsers.
A bunch of misc utils basically reimplement the daemon() function (the
whole fork/close/chdir/etc...). Rather than do that, use daemon() as
that will work under nommu Linux systems that lack fork().
