udev_device.c: consider device valid even if no subsystem symlink exists
...
Some devices may not have subsystem symlinks, therefore we cannot rely
on that to check if device is valid. Instead, check uevent file which
should be always present in valid device.

udev_device.c: correctly handle multiline sysattrs
...
Changed arbitrary size of sysattr to PAGESIZE[0]. Not sure about binary
sysattrs because they may be > PAGESIZE. Either way, we need dynamic
allocation to handle them.
Trim only trailing newlines, not the first one. Now content of the
sysattr not getting truncated. By the way, do we need to trim carrige
return '\r' too?

> The buffer will always be PAGE_SIZE bytes in length. On i386, this
is 4096.
