On NetBSD, time_t has for a long time now been __int64_t.
On 32-bit CPUs, the compiler is not obliged to define
__sync_bool_compare_and_swap_8, so instead this ends up
as an undefined symbol when linking rsyslog. This makes
the code fall back to the pthread / locking method on these
systems, but at least lets the program build.
shave tranforms the verbose autotools output into a pretty Kbuild-like
one which makes it easier to spot warnings.

By default, shave is disabled and you have to explicitly enable it via
./configure --enable-shave.

To unclutter configure.ac and to make it easier re-usable, move the check
for atomic operations into a separate m4 macro file and call the macro
RS_ATOMIC_OPERATIONS (RS for RSyslog)
