Fix some more straggling stuff

* HWCODEC bootloaders

* Remove references to thread structures outside the kernel. They are
private and should not be used elsewhere. The mrobe-100 is an offender
that gets squashed.

* The ata.c hack stuff for large sector disks on iPod Video gets squashed
for the same reason. I will no longer maintain it, period; please find
the real reason for its difficulties.
