This commit also add braces to all `if` statements.

Previously it was possible for fragmentation to occur and as a result
certain allocations would have a linear virtual address space but not a
linear physical address space. This is bad since a lot of calls to
kmalloc_align rely upon both being linear, it has now been changed such
that all allocations done by kmalloc_align now guarantee this mapping
holds for both virtual and physical addresses.
It was due to oversight and sheer luck that this had been working for so
long.

Currently this is just a improvement of error handling but it should
also try to free up memory where it is possible.

This caused certain addreses which where not RAM memory to be assigned
to virtual addresses incorrectly. This caused a significant slowdown
when running it with KVM due to constantly having to exit the VM if the
OS writes to memory that is not RAM.
This fix increased the performance of KVM significantly and improved TCG
performance.

Currently certain parts of the code are taken from osdev wiki as there
seems to be very little documentation that I can find on how H2D FIS is
structured. Those parts, especially some of the uglier parts of the
example code will be rewritten/changed.

Previously this would be hardcoded but now it can be detected by the
bootloader and passed in via the multiboot header.
|
|
This is to allow both the kernel and the userland to share certain
header files and to make the folder structure a bit more clear.
