Perform accumulation of stats only once (i.e. increasing an actual
counter) and report stats based on differences to previous values,
instead of carrying multiple stats counters for each metric and
resetting each counter to zero whenever stats are reported.
`rtpe_stats` is the global master accumulator.
`_intv` variables are intermediate and local storage for values sampled
from `rtpe_stats` at regular intervals.
`_rate` and `_diff` variables hold stats calculated from `rtpe_stats`
and the respective `_intv` variable whenever the sampling and reporting
occurs.
`stats_counters_calc_diff` is used to calculate stats as differences
between `rtpe_stats` and the last sampled `_intv`
`stats_counters_calc_rate` does the same but calculates a per-second
rate, based on a microsecond duration.

Keep a running lifetime total of all "gauge" type metrics. Also track
the square of the sums of all "gauge" type metrics in order to determine
the standard deviation.

libcs are implementing changes to fix the year 2038 issue on 32 bit
platforms (see [1]). musl libc already went ahead and implemented it,
starting with musl-1.2.0 (see [2]).
This commit adds a new definition to lib/loglib.h:
TIME_T_INT_FMT
If __USE_TIME_BITS64 is defined (by a time64 libc, see [1]), it's set to
the proper conversions for type int64_t, PRId64. If __USE_TIME_BITS64 is
not defined, the status quo remains unchanged ("%ld" is used).
The new definition is used in the different parts of rtpengine, where
appropriate.
Note: Richard confirmed that the "%u" format in daemon/cdr.c is not
needed, so this gets swept under the rug.
These changes get rid of the new warnings that appeared with musl-1.2.0.
Below an example warning:
