Title: RFC: a couple of file api tweaks

* Change `fullfile` to match matlab:

```jlcon
julia> fullfile("a","b","c")
"a/bc"
```

```matlab
>> fullfile('a','b','c')

ans =

a/b/c
```

In other words, define `const fullfile = file_path`.

* Rename `real_path -> realpath`, as it's a call to the POSIX `realpath` function, and that's what python, ruby, and perl call it.
