kernel, luna: Port non-VFS changes over from pull request #22
...
continuous-integration/drone/push Build is passing
OwnedPtr, SharedPtr: Add operator bool
Option, Result: Make try_move_value() non-const since it modifies the Option
kernel: Switch to a stack we control for the main task as soon as we leave early boot
Heap: Fix GPF caused when making many small allocations
Heap: Avoid accessing a block after it's potentially deleted
luna: Skip UBSAN.cpp in CMakeLists as that's not implemented yet
luna: Use spinlocks in the heap implementation
kernel, luna: Move Spinlock.h to luna
Option: Use __builtin_launder to ensure that the compiler doesn't label this as UB
SharedPtr: Implement make_shared using adopt_shared
SharedPtr: Delete ptr on failure in all adopt_shared* functions

Kernel: Make a UserVM wrapper around Bitmap and use that to allocate user VM

This lets us allocate more than one page of memory from the user side.

continuous-integration/drone/push Build is passing
Only supports one-page allocations and doesn't have libc wrappers, which means it has to be invoked using syscall().

Bitmap: Introduce a new method 'find' and use it in MM and KernelVM
...
continuous-integration/drone/push Build is passing
This method looks for the first bit with a value, optionally from a starting index, and returns its index.
This should be (haven't benchmarked) way faster than the manual way,
AKA what MM and KernelVM were doing.
This is due to this method using bit and byte manipulation tricks instead of just calling get() until getting the desired result :)

It's also mapped into virtual memory instead of directly going into the physical location!!

For real this time, turns out me, being dumb, added it to Luna instead of the kernel.

Kernel: Add a heap memory allocator
...
This is the first time I've actually dropped liballoc in favor of writing my own implementation.
Usually, malloc() and such looked so complicated that I preferred to let a nice external library do the job.
But I've decided to try writing my own allocator, and now we have heap memory without any 3rd party code!
