When creating the user space binaries I forgot about their proper names,
which is funny on its own. Anyways, let's get them the name they were
intended.

Add basic parsing for underlying ELF executables2024-11-22T06:58:15ZMiquel Sabaté Solàmikisabate@gmail.com2024-11-22T06:58:15Zurn:sha1:8231af9d8d759ae89c8214ca2410b0feab9dfb8c
The given initrd is a CPIO archive of multiple ELF executables. We are
already able to parse the CPIO archive to detect where each file is
located, this commit adds the mapping for each ELF executable to the
corresponding task_struct.
Note that this is still heavily under construction, since we cannot
simply jump into the entry point of an executable as we have not yet
setup the proper layout from performing context switches.

usr: Bootstrap the initramfs for the kernel2024-11-18T14:56:37ZMiquel Sabaté Solàmikisabate@gmail.com2024-11-18T14:56:37Zurn:sha1:d79436a1170e4d5ffde77416313587f320c8e590
Introduce a sample `foo` program which already calls the
`write_and_block` system call which is yet to be implemented by this
kernel. Moreover, the same CPIO format is used for the initramfs as with
Linux, so we can pass it with QEMU without worries.
