Missing `clock_gettime(CLOCK_MONOTONIC)` (e.g. for iceweasel)

It could be a mere matter of extending the mappable clock: add it to
`mapped_time_value_t` in gnumach, handle it in `gnumach/kern/mach_clock.c`, and
make `clock_gettime` use it.

BTW, also make `gettimeofday()` use it, since it's way more efficient and some
applications assume that it is.

What about adding a nanosecond-precision clock, too?  --[[tschwinge]]

IRC, freenode, #hurd, 2011-08-26:

    < pinotree> youpi: thing is: apparently i found a simple way to have a
      monotonic clock as mmap-able device inside gnumach
    < pinotree> currently, in kern/mach_clock.c there's a variable 'time',
      which gets increased on clock interrupt, and optionally modified by
      host_set_time
    < pinotree> ()
    < pinotree> if i add a new variable next to it, only increasing it on
      interrupt but not modifying it at all otherwise, would that give me a
      monotonic clock?
    < pinotree> at least on sme basic tests i did, it seems it could work that
      way
    < youpi> yes, it should work
    < braunr> sure
    < youpi> and that's the way I was considering implementing it
