[PATCH] Libsysfs updates

Please find attached a _BIG_ patch to update udev's libsysfs. Patch applies
on udev-021 and contains:

1. Updates to get udev's libsysfs to the latest (to be released) level.
2. Changes for C++ compatibility (use "char" and not "unsigned char"
	unless absolutely necessary).
3. More importantly, take care of buffer overflows. Libsysfs now uses a
        scaled down version of Kay's "safe" macros.

Tested using a usb-storage device.

I will send you a doc update shortly.
