Add process UI tab entry to show flows statistics per pid.
Also changed flow_entry which now has pointer to new struct proc_entry
object which contains process related info.
On each 1 second refresh proc_entry is checked if it exists by checking
/proc/<pid> path, and is deleted if there is no any flows related to it
(flows_count is 0), if the process exists then dst & src rates info is
zeroed and summed from the all related flows which are in the
proc_entry->flows list.
The bytes & pkts amount info is collected during all the time process
exists.

Add proc_find_by_inode() in proc.c which finds pid by inode & gets
processe's command line and use it in the flowtop.c instead of
walk_processes().

Add proc_exec function which executes given process with
argv list via fork + execvp.
It allows to replace 'system' call approach which is used
for invoking cpp and securely extend it with additional options
like -D.

flowtop and the netsniff-ng's netlink message dissector both need to get
the process name for a pid from /proc/<pid>/exe, thus move that
functionality to an own function.

Move them out of xutils, so that we can maintain them separately.
Also simplify things a bit.
