core: Reserve kernel physical pages + provide our own stack
...
This solves a very weird bug that occurred when we allocated a page that was already used for the stack.

core: Reserve multiboot tags and module memory + load all modules as independent threads instead of just init
...
Only init is started though, other modules are left in a dormant state so init can do whatever it wants and adjust them according to its needs before running them.

core: Add "tokens" to determine what processes can call which syscalls

core+init: Instead of exporting an "arch" symbol for platform-specific code, use "usingnamespace".
...
This makes imports of platform-specific files way cleaner.

c1956748f3
core: Add a struct named "platform.Registers" to cover different architectures
...
This replaces the architecture-independent usage of InterruptStackFrame, which is an x86_64 implementation thing.

core: Add global FrameAllocator with locking

614ed80980
core: Add a simple ELF loader
...
We only need the ELF loader for init, and possibly a few other modules. The bulk of loading executables is going to be done by userspace, so we only need the basics here.

core: Enable interrupts in platformEndInit()
...
This way, each architecture can re-enable interrupts whenever necessary
