Subject: Consolidate the non-canonical epoch timers, like cpuid and Win32's
 QueryPerformanceCounter, into an entropy source hres_timer. Its results, if
 any, do not count as contributing entropy to the poll.

Convert the other (monotonic/fixed epoch) timers to a single function
get_nanoseconds_clock(), living in time.h, which statically chooses
the 'best' timer type (clock_gettime, gettimeofday, std::clock, in
that order depending on what is available). Add feature test macros
for clock_gettime and gettimeofday.

Remove the Timer class and timer.h. Remove the Timer& argument to the
algorithm benchmark function.
