Use the object crate for panic backtraces
...
This increases the kernel image size by about 16kb, but in return
significantly simplifies things.

Replace the log crate with a custom logging system
...
This avoids the need to explicitly set a logger early during boot, which
reduces the amount of moving parts that could go wrong slightly. And it
cuts the kernel image size by 13kb.

Use HashMap rather than BTreeMap for scheme handles
...
According to the comments this previously wasn't done due to hashbrown
not having a const constructor. While it is true that HashMap::new() is
not const, HashMap::with_hasher() is const. HashMap::new() becoming
const is likely blocked on const traits.
This shrinks the kernel image by about 35kb.
