dc527a3619 Rust 1.56 results in a bigger loader. Presumably because "optimization". 
This causes the font maps to shift down. Allocate some "room to grow"
as Rust gets more "optimal".

e93929e04b loader: use vendered version of utralib

This will be removed when Rust 1.55 is released and we can bring the
`loader` package back into the main workspace.

4c777976ac clear RAM on a cold boot 
since the RAM is battery backed and persistent, it's probably
a good idea just to zero-ize it before using it on a cold boot.

8b06017c66 loader: fix double-allocation of memory regions 
Due to an error in how small regions were loaded, memory was mapped to
the wrong offset. This didn't affect us for the most part, since these
small regions were mostly in the backtrace report which we don't usually
hit.

With this patch, we now can verify that processes are loaded correctly.
For example:

    (gdb) compare-sections
    Section .rodata, range 0x100e0 -- 0x13bdc: matched.
    Section .eh_frame, range 0x13bdc -- 0x15040: matched.
    Section .text, range 0x16040 -- 0x2dd6e: matched.
    Section .sdata, range 0x2ed70 -- 0x2ed78: matched.
    Section .data, range 0x2ed78 -- 0x2eda4: matched.
