Tomas Janousek 7c3f1a5732 Introduce boot based time 
The commits

  411187fb05 (GTOD: persistent clock support)
  c1d370e167 (i386: use GTOD persistent clock
    support)

changed the monotonic time so that it no longer jumps after resume, but it's
not possible to use it for boot time and process start time calculations then.
 Also, the uptime no longer increases during suspend.

I add a variable to track the wall_to_monotonic changes, a function to get the
real boot time and a function to get the boot based time from the monotonic
one.
