[dev] Implement raw partition scanner (MBR+GPT)
Relying in udev has proven unsuitable time and time again.
Sometimes after switchroot, it loses information about partitions that
was already present in the initramfs. When an MBR partition contains a
filesystem that is larger than the partition, the udev info is missing
the MBR partition type from its output (observed with NTFS at least).
As the kernel doesn't expose the mbr type and gpt type GUID directly in
sysfs, we implement our own crude MBR and GPT parsers. In ash.
