Revert "Set BFQ scheduler as default [...]"

BFQ doesn't apply to current git, so we'll switch to deadline.

This reverts commit 903038b6fb60c178ed67c769aa918c8842d0b11e.
Switch to deadline I/O scheduler for now
Initial enabling of TuxOnIce
Disable TuxOnIce for now (and rework some more)
Don't append configuration checksum to version

This causes massive ccache misses every time it changes.
Build TuxOnIce into the kernel trying to fix build
More debugging: also build in TOI file allocator

Before these two last commits, I was getting undefined module symbol
errors. This one *should* fix resume_file, the last one remaining.
Support only compressed swap, remove UI
Add app-misc/ftop-1.0
