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.

kernel: Add a fun splash screen during boot :)

Mostly for fun.
Has a lot of delay in order to see the actual splash screen.

Add a VERY BASIC and hacky way of allocating memory from userspace
...

Only supports one-page allocations and doesn't have libc wrappers, which means it has to be invoked using syscall().

libc: Implement time() using clock_gettime().
...
continuous-integration/drone/push Build is passing
The cool POSIX kids use clock_gettime() now because it has NANOSECONDS (and different clocks!),
but ANSI C prefers this function.
We can still implement it based on clock_gettime(), we just have to discard the NANOSECONDS.

Of course, using <luna/Format.h> makes it so simple. No need for duplicate code!

Switch to C for userspace, with a very bare-bones libc!!
