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

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.
