a7a5c5aa0d Kernel/IPC: Partially implement MappedBuffer translation. 
Right now only MappedBuffers that only span a single page and are not aligned are implemented.

MappedBuffers are unmapped during the reply part of ReplyAndReceive. Only unmapping of ReadOnly buffers is currently implemented.

e4f35f70ac Memory: Added a function to change the memory state of an address range. 
This will be useful when implementing memory aliasing operations.

6d2734a074 Kernel/Memory: Give each Process its own page table. 
The loader is in charge of setting the newly created process's page table as the main one during the loading process.

ebdae19fd2 Remove empty newlines in #include blocks. 
This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.

5c5cf2f8e0 Core: Properly configure address space when loading a binary 
The code now properly configures the process image to match the loaded
binary segments (code, rodata, data) instead of just blindly allocating
a large chunk of dummy memory.

0a60aa75c2 Kernel: Add VMManager to manage process address spaces 
This enables more dynamic management of the process address space,
compared to just directly configuring the page table for major areas.

This will serve as the foundation upon which the rest of the Kernel
memory management functions will be built.
