build_and_run script, fix build.rs sometimes using the wrong
architecture, add badapple ELF and change default font size to 1 for it
to work, improve framebuffer errors, remove unnecessary commands from
make and improve debug filtering
remove incorrect timer frequency set, fix interrupt handler not
restoring stack ptr, handle both user and kernel aborts, remove aarch64
ps2 support, fix ELF code mapped as code making it unwritable, add
assets.rs to handle both arches automatically, make PS2 x86_64
compatible with linux keycodes, always try printing kernel panic to
serial
FRAME_ALLOCATOR global, make XunilFrameAllocator not hold Limine entries
so it can be used without lifetimes, implement the process struct, add
user heap by giving back heap_start from ELF and adding sbrk syscall,
align ELF loading in userspace_stub, implement lots of libc functions in
libxunil, remove x86_64 dependency from libxunil, add malloc and all
required heap functions to libxunil and more syscall numbers, add a util
file to libxunil, add build scripts for libxunil and doomgeneric
