Load the bootstrap blob at 4096 instead of 0
...
This way the NULL page can stay unmapped and the bootstrap code can
avoid UB when reading the initfs header (which is at the start of the
bootstrap code.

Fix UB in the locking code of context switching
...
The spin crate considers it UB to call force_write_unlock while there is
a threads trying to obtain a read lock on the same rwlock.
This also switches to the spinning_lot crate for the context rwlock as
it has support for a write guard keeping a reference to the rwlock using
an Arc instead of a reference.
