a02925055c Remove cycle between process and host packages 
gopsutil is a transitive dependency of another project that I am integrating
into an internal build system. We target multiple platforms and as a part
of the build system for the large internal repo, we calculate the build
graph used to determine what targets have changed and need to be build /
tested as a single DAG for all platforms.

gopsutil currently does not form a DAG if linux and any other platform are
considered at the same time. linux is the only platform where the process
package imports the host package.

To remove this cycle, the relevant methods have been moved to internal/common
with the linux build tag and are consumed the host and process packages.

b3670f8027 Add hour handling in convertCPUTimes function 
This commit add hour handling in convertCPUTimes function.

The time string usually comes from macOS command line:
ps -a -o stime,utime -p <pid>

which could contain hour string.

e5ca4477a1 [process][windows] WIP #586 use win32 API in process.Exe but fallback on WMI 
This method only lets a 32bit program get other 32bit processes exe path
and a 64bit program get other 64bit processes exe path, so we fallback to
the slow (but kind of reliable) WMI calls if we can't access to the other
process module.

6b539051d2 [process][windows] Use win32 API in process.Children() instead of slow WMI call 
The CreateToolhelp32Snapshot+Process32First+Process32Next combo already
iterates over all processes, so it would be inefficient to enumerate all
processes with process.Processes() and then calling p.Ppid() on each of
them: we just use this combo to get all processes and their ppid in a
single iteration.

This is faster by a factor of 25 compared to the previous WMI call.

413cb32b6c Use static initialisation for invoke instances, instead of init funcs 
The order of init function execution is dependant on the order that the
source files are passed to the compiler. This causes issues when
building under other build systems, such as bazel or buck, as they are
not guarenteed to maintain the same file order as the default go tool.
