LibC+userspace: Make everything compile with -Wall -Wextra -Werror
...
I added -Wall -Wextra -Werror as public compile flags to libc. Now
everything in userspace in compiled using these flags. I made all
necessary changes to allow compilation to work.
Only exception is execvp which has a large stack usage. Maybe it
should use malloc for the buffer but posix allows ENOMEM only when
kernel is out of memory... This can be fixed when fexecve is
implemented and there is no need for absolute path.

Move tree building to its own function. Both parts can use the same

Second part was kinda weird. You are supposted to assume something
