This is an update of my previous patchset [1].  The main driver of this
change is to move away of using 32-bit timestamps and for syslog() it
would require to use an ad-hoc format.  Instead, since RFC5424 does
define a better way to format the timestamp, it is used instead.

Along with the RFC5424 change, the patch simplifies the code to use
a static buffer on default case (so no dynamic allocation for messages
up to 1024) and add a proper syslog() testscase.
