more faster

I rework my patch to use struct xfile instead of struct kinfo_file.
struct kinfo_file - causes to read many info, in case files on non local fs
this produces traffic and lags.
For example I open in thunar /usr/ports/devel mounted on NFS, and same folder
mounted via sshfs, and got ~9000 opened files descriptors.
Then while I try to open any file thunar make call fdwalk() and it freeze on
sysctl(CTL_KERN, KERN_PROC, KERN_PROC_FILEDESC) 5-10 seconds, and this happen 2
times, so total freeze time starting from 10 second per one opened file.

struct xfile have less info/size and does not cause any side effects.
