Details:

We have already talk in several threads to add such concept in sys_arch.

This feature could be used to fix:

- improve timeouts accurate (see https://savannah.nongnu.org/bugs/?1902 and
some others).

- snmp_sys_time consumne lot of cycles for nothing (since, with current
implementation, we have to call snmp_inc_sysuptime() each 10ms), which is not
useful, since we could compute "sys_time" only when snmp_get_sysuptime is
called (see https://savannah.nongnu.org/patch/?5785).

Nothing was really decide about that. Thoughts?
