kernel: Update the VM allocator for userspace to use a linked list
All checks were successful
continuous-integration/drone/push Build is passing
Details 
This can cover the entire address space at once in a more memory-efficient way.

Stress-tested using 'base64 /bin/ls' which allocates enough contiguous
virtual memory to store the entirety of /bin/ls :)

A couple of bugs and fixes later, here we are!

kernel: Do not automatically read the MBR partition table from /dev/cdrom

kernel/ATA: Read the CDROM's first sector using ATAPI PIO!!

This is a problem, as PIO is inconvenient. But hey, it works for now!
