Merge pull request #649 from shirou/feature/fix_648_freebsd_mem 
[mem][freebsd]: add SysctlUint which can adapt both 32 and 64 bit

Fix cpu stats when hw.smt is enabled 
When hw.smt is enabled, and it's enabled by default from 6.4, the
number of cpus given by `runtime.NumCPU()` is half of the total: only
the cpuN with N = 0,2,4,... are used by the system. We need to detect
that and ask for the correct stats.

[cpu][linux] Add support for logical arg in Counts #640 #628

Get hw.ncpuonline without unix.SysctlUint32 
unix.Sysctl always return an error when asking for hw.ncpuonline, so
revert to a direct unix.Syscall6 to get the cpu count.

fix logic error + little refactor 
Fix: get cptime of n-th cpu when `percpu` instead of the average.

While there, rearrange the last if statement to make the code a bit
more homogeneous.

Lomanic 974d52d412 [load][darwin] Remove calls to sysctl binary in load/load_darwin.go #639 
Again, a simple benchmark:

Lomanics-iMac:~ lomanic$ time ./load_avg.old ; time ./load_avg
{load1:0.89,load5:0.99,load15:1.01} <nil>

real    0m0.019s
user    0m0.008s
sys     0m0.013s
{load1:0.8876953125,load5:0.98828125,load15:1.0146484375} <nil>

real    0m0.011s
user    0m0.004s
sys     0m0.006s

This is faster and yields more precise results.
