Optimize mmu handling

Previously there was two complete L1 mmu tables where one was only
used when kernel mapping was active and the other when user mapping
was active too. In addition to that there was several sets of L2 mmu
tables which where unused.

Now there's only one complete L1 mmu table shared by all CPUs. There's
one small L1 mmu table for each thread used to keep user mappings. The
small L1 mmu tables takes each 128 bytes and can spans 32 MiB of
virtual memory.

This change saves memory ~32 KiB, but also prepares for multiprocessing
since each thread has its own user mapping.

Due to the change of mmu table handling many low level assembly and C
functions are changed, and some even removed.
