fs: implement infrastructure for an 'exists' function
This could be used in scripts such as:
if test -e mmc 0:1 /boot/boot.scr; then
load mmc 0:1 ${scriptaddr} /boot/boot.scr
source ${scriptaddr}
fi
rather than:
if load mmc 0:1 ${scriptaddr} /boot/boot.scr; then
source ${scriptaddr}
fi
This prevents errors being printed by attempts to load non-existent
files, which can be important when checking for a large set of files,
such as /boot/boot.scr.uimg, /boot/boot.scr, /boot/extlinux.conf,
/boot.scr.uimg, /boot.scr, /extlinux.conf.
