initramfs-uniboot: Add support for early-init plugins.
* Extend plugin protocol: plugins matching pattern '0*' are early-init,
executed ASAP after boot, before kernel command and block devices are scanned.
And thus, they can affect parsing of kernel command line (by overriding $CMDLINE)
or detection of block devices (e.g. by loading additional modules).
