kernel+libc: Start interfacing with the VFS from userspace (open & close)
...
This commit adds open and close syscalls to the kernel, and adds matching wrappers to libc.
No read/write support, so file descriptors are kind of useless for now.

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 :)
