2022-07-18syscalls: implement execbufdzwdz
i have been planning to implement something like this for a while now. it should be faster when doing consecutive syscalls (to be tested). it will also be helpful in writing the elf loader

2022-07-10syscalls: implement dupdzwdz
2022-07-10init/lib: implement "evil semaphores"dzwdz
I started implementing native semaphores in the kernel, but then I've realized that I can implement them in userland using pipes. Thus, this hot garbage was born.
