implementation, running support, also basic syscalls to test if it
works. add a syscall ABI and a new libxunil ABI for calling back to the
kernel with syscalls, add user mode protection when running ELF, add TSS
Privilege Stack table to fix GPF issues, add invalid opcode handler, fix
rust panics using rectangle_filled instead of fb clear. Also add a hello
world example binary that runs in usermode at startup.
add mouse support and interrupts on x86_64 using a ps2 mouse which
needed pic unmasking, add span filling to framebuffer, add back
without_interrupts to serial console and framebuffer, add a mouse
rectangle which tracks the mouse position and test the performance of
the drawing.
set PIT interval to 1000hz, use a vector inside Framebuffer, remove
without_interrupts from the framebuffer and serial console, move to
usize on primitives, add date at boot and turn on multithreading, add a
boot animation and add a test_performance function with the new timer
frame allocator optimizations, make a basic init function in arch that
will initialize everything for a given arch. Add tests in kmain for
alloc, and add a Locked struct used for static mutables and the linked
list.
