The fs interface functions should now return a "status_t" rather than an "int".

Added syscalls for, and implemented sys_create_link(), sys_remove_dir().
Implemented link(), unlink(), rmdir().
Fixed the inconsistent path buffer handling in the user|sys vfs functions; the
path buffer is now exactly SYS_MAX_PATH_LEN from userland (incl. terminating
null byte).
