stuart nelson e942d7e234 Maintain granularity in cpu data 
Export cpu mode times as original uint64_t data,
and update frequency, and do the conversion to
float64 and subsequent division in go.

stuart nelson 78c84b1a47 Remove old freq finding code 
This is the code that was lifted from the freebsd
implementation, but was not correct.

stuart nelson 45ac033d9e Use correct frequency for calculating cpu time 
The correct frequency is the systimer frequency,
not the stathz.

From one of the DragonFly developers:

The bump upon each statclock is:
((cur_systimer - prev_systimer) * systimer_freq) >> 32

systimer_freq can be extracted from following
sysctl in userspace:
sysctl kern.cputimer.freq

stuart nelson 9f7822ccdc Remember to bzero string 
Duplication was caused by malloc returning a
region of memory that already had data in it.

stuart nelson 3e4a154656 Correctly exporting values 
Moved to exporting via a string, which is then
split and parsed.

The string is sometimes duplicated, however.
